Adsorption-desorption data obtained by batch equilibration method in three Indian soils of different agro climatic regions (Almora, Uttra Khand; Jhargram, Kolkatta, West Bengal and IARI, New Delhi) at a concentration range from 2 to 10 μg mL−1 fitted well in the Freundlich adsorption equation. Highest adsorption was observed in Almora followed by IARI and Jhargram soils, and was explained on the basis of Kocvalues of 1236.86, 780.51 and 539.64 respectively and 1/n values of 1.77, 1.02 and 0.68 respectively. Desorption followed the reverse order. Hysteresis was positive for Almora and IARI soils (H=0.50 and 0.99 respectively) and negative for Jhargram (H= 2.24).
