El pasto vetiver se puede utilizar para estabilizar terrenos, construir jarillones en ríos y quebradas, estabilizar barrios en peligro, recuperar humedales, descontaminar aguas residuales, repeler insectos y roedores, y regular el agua en pozos. Se siembra a 10 plantas por metro lineal a 15 cm de profundidad con materia orgánica, y requiere mantenimiento cada tres meses. El vetiver tiene una raíz profunda que puede alcanzar los 5 metros de profundidad en tres años, lo que lo

REMOVAL PARAQUAT FROM AQUEOUS SOLUTIONS WITH ZEOLITE NANOPARTICLES OPTIMIZED ...EDITOR IJCRCPS
Nowadays, much attention for using chemicals as adsorbent for removal herbicide from aqueous solution has been aroused.
Zeolite as low-cost adsorbent was used in this paper for removal paraquat from water. Iran has a variety resources of zeolite.
Zeolite was collected from Semnan region and after modification, zeolite nano-particles was used for adsorption. Box-Behnken
experimental design was used for simplifying and optimizing the experiment condition. Three factor was studied in this paper; pH
(6-8), temperature (25-45◦C) and the amount of adsorbent (0.5-2 g). The residue of paraquat after each experiment was
determined by injection of 250 μl of each sample to HPLC equipped with column (150mm×4.6mm, ODS (C18)-H-OL), UV-detector
at 258 nm. The mobile phase composition was a mixture of tetramethylammonium hydroxide pentahydrate and ammonium
sulphate in ultra-pure water and adjusted to pH 2 with sulphuric acid. According to BBD the optimum condition was pH 6,
temperature 45◦C and 2 g of adsorbent. At this condition the removal efficiency was about 80%. The results of this study showed
thatby increasing the pH, the percentage of removal was decreased. However, the higher temperatureslead to more removal
capacity of zeolite nano-particles but it was not statistically significant.
Keywords: Paraquat, Zeolite, Box-Behnken design, HPLC.
ACETYLATION OF BENZYLIC ALCOHOLS OVER BiFeO3 (BFO), Bi0.86Sm0.07Eu0.07FeO3 (B...EDITOR IJCRCPS
BiFeO3 (BFO), Bi0.86Sm0.07Eu0.07FeO3 (BSEFO), and Bi0.86Sm0.07Cd0.07FeO3 (BSCFO) nanopowders were prepared by the sol-gel
combustion method and the catalytic performances were evaluated in acetylation reaction of benzyl alcohol. The physical chemical
properties of catalysts were characterized by using XRD, FT-IR, scanning electron microscope (SEM), EDX and BET surface.
Efficient acetylation of benzyl alcohol was carried out over all the nano powders using acetyl chloride/ acetonitrile at room
temperature. Among the nanopowders, BSCFO showed the highest catalytic performance and the yield of benzyl acetate was 89,
45, and 69 percent over BSCFO, BFO, and BSEFO, respectively. Partial substitution of Sm-Eu and Sm-Cd in bismuth ferrite
improved the catalytic performance and increased the specific surface area of the catalysts. A direct relationship was resulted
between catalytic performance and surface of catalysts, where BSCFO with the highest surface area (111m2/g) exhibited the
superior catalytic performance. The quantitative yield for acetate product was also resulted for acetylation of p-methyl benzyl
alcohol, p-nitro benzyl alcohol and p-chloro benzyl alcohol on BSCFO. The catalysts showed good reusability in the process. The
study confirmed the catalysts could be promising catalyst for acetylation of alcohols.

PREPARATION AND UTILIZATION OF EMULSIFIERS IN SWEET BISCUITSEDITOR IJCRCPS
Emulsifiers have been prepared by blending soymilk , skim milk powder and baby food with combination of lecithin and glycerol
mono-stearate along with sorbitol, sodium benzoate and water. Analysis of emulsifiers have been carried out for pH, moisture
content, total solids content, acetone insoluble content, acid value, viscosity and percent stability. Samples of biscuits were
formulated varying the amount of emulsifier with constant amounts of whole wheat flour, hydrogenated fat, sugar, sodium
bicarbonate, ammonium bicarbonate, skim milk powder and strawberry. The biscuits were analyzed for carbohydrate content,
protein content, fat content, ash content and moisture content along with standard biscuits. Sensory evaluation of biscuits was
carried out by 9 point Hedonic scale score-card method taking into account attributes such as texture, taste, flavor and overall
quality. It was observed that good quality biscuits could be prepared from the prepared emulsifiers. It is suggested that the
emulsifiers prepared may be useful for other bakery products such as cake, cookies, bread etc.,

Rice is one of the most important crop in the world.
The main production countries are China, India, Indonesia, Bangladesh, Viet Nam. Becides the Asian countries, rice is also welcomed as staple food in South America and Africa countries.
Weed control is important in rice cultivation. Main weeds are grassy weed, broadleaf weed and sedges.
Usually, the emergence of grassy weed is ealier than other types of weeds and the damage is heavier. Echinochloa spp is a big problem as main grassy weed in rice field.
Here are some several herbicides suggested for weed control in rice field.
Control of grassy weeds: Oxaziclomefone, Bispyribac-sodium, Cyhalofop-butyl.
Control of broadleaf weed and sedges: Bentazon, Bentazon + MCPA.
Pre-emergence is a cost-effective way, here are several combinations: Bensulfuron-methyl + Metolachlor, Bensulfuron-methyl + Pretilachlor, Bensulfuron-methyl + Mefenacet.
