Adsorption-desorption behaviour of chlorimuron-ethyl herbicide on homoionic clays

Abstract

Laboratory studies were conducted to determine the adsorption-desorption behaviour of Chlorimuron-ethyl herbicide on three homoionic clays (Kaolinite (K), Mica (M) and Bentonite (B)), which are found in Indian soils. The adsorption- desorption data of chlorimuron-ethyl fitted well to Freundlich adsorption- desorption isotherm model (R² = 0.755 to 0.986). The computed valued of log K and 1/n varied from 4.0199 (B-Cu) to 4.1144 (B-Ca) and from 0.4458 (M-Cu) to 0.7894 (K-Ca) respectively. Desorption data of chlorimuron-ethyl were also fitted to Freundlich model and the values of log K' and 1/n' ranged from 4.2727 (K-Ca) to 4.2933 (M-Ca) and from 0.0006 (B-Cu) to 0.0033 (B-Ca), respectively. Higher values of desorption index n'/n indicated poor reversibility of chlorimuron ethyl by soil clays.
