Lecturer,
Environmental Department, College of Engineering, University of Babylon
ABSTRACT
In this study modified agricultural residus, orange peel was examined as sorbent to remove
reactive red 3BF from aqueous solution. To modify its sorptive characteristics, orange peel was
treated with HCL. This study on adsorption of reactive red 3B was conducted by using batch
experiment by varying various parameters such as contact time, PH and amount of adsorbent. The
percentage of adsorption of RR3B on top was found to be 93.6 at initial concentration of (50PPM).
Treated orange peel was found to be very effective and reached equilibrium in the 2.5hr. The
percentage of adsorption decreased with increase in the PH and showed the maximum removal of
reactive red in the range (4-6) pH , Also it was observed that the removal efficiency of reactive dye
increase with increasing adsorbent dose and contact time. The freundlich and Langmuir isotherm was
employed and their isotherm constant wascalculated. The experimental data fitted well with the
Langmuir and freundlich adsorption isotherm. The result indicated that the treated orange peel could
be alternative material of more costly adsorbent used for dye removal.
Keywords: Orange Peel, Reactive Red, Isotherm Model.
1- INTRODUCTION
Dyes are chemicals, which on binding with material will give colour to them. Dyes are ionic
aromatic organic compound with structure including aryl rings, which have delocalized electron
system. The colour of dye provided by the presence of chromophore groupe. A chromophore is a
radical configuration consisting of conjugated double bond containing delocalized electrons. The
Chromogen, which is aromatic structure normally containing benzene, naphathalen or anthracene
ring, is a part of chromogen –chromophore structure along with an auxochrom. The presence of the

ionizing groups known as auxochrom result in a much stronger alteration of maximum absorption of
compound and provide bonding affinity (Velmurugan .P ,2011).
Many dyes and their break dawn products may be toxic for living organism therefore
decolourization of dyes is an important aspect of wastewater treatment before discharge.
conventional method such as a chemical precipitation, chemical oxidation or reduction, filtration,
electrochemical treatment, ion exchange, adsorption, membrane processing and electrolytic methods,
have been traditionally employed for colour and heavy metal removal from industries waste water,
(tobin and roux, 1998).
However the shortcoming of most of this methods are of high operational and maintenance
costs, generation of a toxic sludge and complicated procedure in the treatment involved in the
treatment. Comparatively, adsorption process is considered better in the water treatment because of
the convenience, ease operation and simplicity of design, (faust and ally, 1987).
A number of non- conventional low cost adsorbent used for dyes removal include fruit waste
of the prosopisnjuliflora, wood, waste orange peel, banana pith and bagasse pith etc. Utilisation of
agricultural waste as low cost adsorbent, (M C.Somasekhara Reddy, 2006) the present study is to
explore the feasibility of orange peel as low cost natural adsorbent with respect to the various
parameter such as colour adsorbent capacity of material with initial concentration at different doses
and pH. The adsorption isotherm are plotted to study the removal capacity of material, the study
shows that the material has good potential for the removal of colour from aqueous solution.
Orange peel principally consists of cellulose, pectin, hemicelluloses, lignin, chlorophyll
pigments and other low molecular weight hydrocarbons (Liang, s.et.al.2010). These components
contain various functional groups, such as carboxyl and hydroxyl groups which make the orange peel
to be a potential adsorbent material for removing metal ions from aqueous solution (Arami,.
A.etal.2005).
R.S.Mane and V.N. Bhusari (2012) studies the adsorption process by using the banana and
the orange peel to remove the colour from the waste effluent of textile industry .The material was
obtained and treated for the removal colour at different doses and evaluated for removal of the colour
at different PH.

(2012) use the low cost and eco- friendly adsorbent has
been investigated as ideal alternatives to the current expensive methods for removing dyes from
waste water. Orange peel (OP) was used as a low cost natural waste adsorbent for removal of textile
effluent.

and used for the study.
Orange peel principally consists of cellulose, pectin, hemicelluloses, lignin, chlorophyll
pigments and other low molecular weight hydrocarbons (Liang, s.et.al.2010). These components
contain various functional groups, such as carboxyl and hydroxyl groups which make the orange peel
to be a potential adsorbent material for removing metal ions from aqueous solution (Arami.
A.et.al.2005)
Depending on this phenomenon, this work was aimed on studying the potential adsorption of
orange peel as natural waste material that could provide a successful eco friendly low cost solution
for removing reactive red 3B from aqueous solution. The effective parameters of pH, and contact
time and initial dose of adsorbent were investigate .

5- RESULTS AND DISCUSSIONS
5.1 Introduction
The behavior of treated orange peel as an adsorbent was studied by evaluating the
equilibrium isotherm and removal efficiency of reactive red (3B) in batch. Equilibrium data is fitted
to Langmuir and Freundlich models. The applicability of the isotherm equation was compared by
calculating values (R2
). The effect of various initial dose concentration, pH, and contact time also
was studied.
5.2 Effect of contact time
Figure (5-1) depicts the amount of RR3B removed by treated orange peel at 28°c and PH
(6.4) as a function of contact time. The figure shown dye adsorption at initial stage is quit rabid but it
gradually slows down unit (it reaches the equilibrium).

This is due to the fact that a large number of vacant surface sites are available for adsorption
during the initial stage, and after a lapse of time the remaining vacant surface sites are difficult to be
occupied due to repulsive forces between the solute molecules on the solid and bulk phases (Ahmad
et al, 2009). The equilibrium was attained after shaking for (2.5) hr.

treatment orange peel (TOP)
5-3 Effect of initial solution PH
The pH of the solution affects the surface charge of the adsorbents as well as the degree of
ionization of different pollutants. The hydrogen ion and hydroxyl ions are adsorbed quite strongly
and therefore the adsorption of other ions is affected by the pH of the solution.
The effect of pH on the adsorption of RR3B on orange peel is presented in figure (5-2) .It
shows that the percentage removal of RR3B was maximum at the (pH =4) and decreased with further
increase in pH.

5-4 Effect of adsorbent dosage
Variation of adsorbent dose showed that although increasing of TOP dose in aqueous solution
can result to increased pollutant removal, but this deviation of TOP leads to decreasing of adsorbed
dye per unit of adsorbent (qe), this phenomenon may relate to the use of surface area as unsaturated
form. The q e (mg/g) decreasing from 7.23 mg/g to 1.5 mg/g (figure 5-3).
This result indicates that although mass elevation of adsorbent can provide large or available
surface area, but the adsorption pattern of the pollutant as unsaturated. Form leads to unfavorable
using of adsorbent.
This phenomenon is the most important point for the design of economical and large scale
adsorption devices (Ehrampoush et al, 2011).

5-5 Adsorption Isotherm
Application of Langmuir and Freundlich models to the adsorption isotherm, showed that the
Freundlich and Langmuir isotherm models provided excellent satisfactory with the highest (R2

(0.995 and 0.978). The estimated values for the parameters of these and freundlich are shown in

Hassan Lecturer, Environmental Department, College of Engineering, University of Babylon ABSTRACT In this study modified agricultural residus, orange peel was examined as sorbent to remove reactive red 3BF from aqueous solution. To modify its sorptive characteristics, orange peel was treated with HCL. This study on adsorption of reactive red 3B was conducted by using batch experiment by varying various parameters such as contact time, PH and amount of adsorbent. The percentage of adsorption of RR3B on top was found to be 93.6 at initial concentration of (50PPM). Treated orange peel was found to be very effective and reached equilibrium in the 2.5hr. The percentage of adsorption decreased with increase in the PH and showed the maximum removal of reactive red in the range (4-6) pH , Also it was observed that the removal efficiency of reactive dye increase with increasing adsorbent dose and contact time. The freundlich and Langmuir isotherm was employed and their isotherm constant wascalculated. The experimental data fitted well with the Langmuir and freundlich adsorption isotherm. The result indicated that the treated orange peel could be alternative material of more costly adsorbent used for dye removal. Keywords: Orange Peel, Reactive Red, Isotherm Model. 1- INTRODUCTION Dyes are chemicals, which on binding with material will give colour to them. Dyes are ionic aromatic organic compound with structure including aryl rings, which have delocalized electron system. The colour of dye provided by the presence of chromophore groupe. A chromophore is a radical configuration consisting of conjugated double bond containing delocalized electrons. The Chromogen, which is aromatic structure normally containing benzene, naphathalen or anthracene ring, is a part of chromogen –chromophore structure along with an auxochrom.

Many dyes and their break dawn products may be toxic for living organism therefore decolourization of dyes is an important aspect of wastewater treatment before discharge. conventional method such as a chemical precipitation, chemical oxidation or reduction, filtration, electrochemical treatment, ion exchange, adsorption, membrane processing and electrolytic methods, have been traditionally employed for colour and heavy metal removal from industries waste water, (tobin and roux, 1998). However the shortcoming of most of this methods are of high operational and maintenance costs, generation of a toxic sludge and complicated procedure in the treatment involved in the treatment. Comparatively, adsorption process is considered better in the water treatment because of the convenience, ease operation and simplicity of design, (faust and ally, 1987). A number of non- conventional low cost adsorbent used for dyes removal include fruit waste of the prosopisnjuliflora, wood, waste orange peel, banana pith and bagasse pith etc. Utilisation of agricultural waste as low cost adsorbent, (M C.Somasekhara Reddy, 2006) the present study is to explore the feasibility of orange peel as low cost natural adsorbent with respect to the various parameter such as colour adsorbent capacity of material with initial concentration at different doses and pH. The adsorption isotherm are plotted to study the removal capacity of material, the study shows that the material has good potential for the removal of colour from aqueous solution. Orange peel principally consists of cellulose, pectin, hemicelluloses, lignin, chlorophyll pigments and other low molecular weight hydrocarbons (Liang, s.et.al.2010). These components contain various functional groups, such as carboxyl and hydroxyl groups which make the orange peel to be a potential adsorbent material for removing metal ions from aqueous solution (Arami,. A.etal.2005). R.S.Mane and V.N. Bhusari (2012) studies the adsorption process by using the banana and the orange peel to remove the colour from the waste effluent of textile industry .The material was obtained and treated for the removal colour at different doses and evaluated for removal of the colour at different PH. GurusamyAnnaduriaa et al. (2002) use the low cost banana and orange peels were prepared as a adsorbent for the adsorption of dyes from aqueous solution. A. G. El-Said a and A.M. Gamalb (2012) use the low cost and eco- friendly adsorbent has been investigated as ideal alternatives to the current expensive methods for removing dyes from waste water. Orange peel (OP) was used as a low cost natural waste adsorbent for removal of textile effluent. RESEARCH OBJECTIVE The main objectives of this study can be summarized in the following option: 1- Investigating the removal of the (Reactive Red 3B) from the aqueous solution by using orange peel as adsorbent material bed with different operational conditions. 2- Modify orange peel by pretreatment of row orange peel with HCL acid to enhance adsorption capacity and to investigate the adsorption of RR3BF dye on it. The study including the characteristics of adsorbent and determination the factors affecting the sorption such as contact time, PH and initial dose. 3- Calculation of the adsorption capacity and intensity using langmuir and freundlich isotherm models for the adsorbent.

The equilibrium was attained after shaking for (2.5) hr. Fig. (5-1): Effect of initial contact time of RR3B on the equilibrium adsorption capacity of treatment orange peel (TOP) 5-3 Effect of initial solution PH The pH of the solution affects the surface charge of the adsorbents as well as the degree of ionization of different pollutants. The hydrogen ion and hydroxyl ions are adsorbed quite strongly and therefore the adsorption of other ions is affected by the pH of the solution. The effect of pH on the adsorption of RR3B on orange peel is presented in figure (5-2) .It shows that the percentage removal of RR3B was maximum at the (pH =4) and decreased with further increase in pH.

The q e (mg/g) decreasing from 7.23 mg/g to 1.5 mg/g (figure 5-3). This result indicates that although mass elevation of adsorbent can provide large or available surface area, but the adsorption pattern of the pollutant as unsaturated. Form leads to unfavorable using of adsorbent. This phenomenon is the most important point for the design of economical and large scale adsorption devices (Ehrampoush et al, 2011).
