Abstract

Adsorption of anilofos on six different soil samples was studied using batch shake techniquu. The adsorption isotherm fitted well in Freundlich equation (r2 > 0.98) and Freundllch’’scnstant ‘k’ and ‘1/n’ values were in the range of 3.25 to 6.97 and 0.787 to 0.891, respectively. In different soils, adsorption was in order: Mollisol>Vertisol>Incepttsol>Alfisol2 ≃ Aridisol>Alfisol-1. The amount adsorbed was related to clay, pH and organic matter rontent (R2=0.09). Removal of organic matter by H2O2 oxidation caused drastic reduction in adsorption of anilofos. Sorption of anilofos in different soils was irreversible and only about 17.5 to 31.4% could be desorbed.
