Effect of cationic, non-ionic and anionic surfactants on the adsorption of carbofuran on three different types of Indian soil

Abstract

The adsorption of carbofuran in aqueous surfactant-free and surfactant (cationic, nonionic and anionic) solutions of different micellar concentration on three different types of Indian soil was studied using the batch shaking technique. Higher adsorption of carbofuran in both systems was observed on silt loam soil followed by loam and sandy soils. The affinity of carbofuran towards organic matter and the clay content of the soils was evaluated by calculating the Kom and Kc values, when it was found that carbofuran adsorption was better correlated with the clay content than with the organic matter content.
