Abstract:Adsorption of α-HCH、β-HCH、γ-HCH和δ-HCH by modified organo-diatomite (OD),which was modified by cetyltrimethylammonium bromide (CTMAB) was stadied. The cationic surfactant could bring the better adsorption efficiency of HCHs than using the raw diatomite. According to the partition coefficient (Kow), the adsorption efficiency of the four HCH onto OD followed the order: δ-HCH >γ-HCH>α-HCH>β-HCH. The four isotherms were selected to model the adsorption behavior of HCH onto OD. The best fit for the experimental adsorption data were given by the Redlich-Peterson model.
