Abstract

Colloid is one of the important factors to affect the migration and transformation of organic pollutants in soil. Take SiO2 sol and Fe(OH)3 as the study objects, the adsorption characteristics of BHC with SiO2 sol and Fe(OH)3 colloid in the groundwater were studied. The results showed that with the existence of colloid, the order of distribution coefficients for benzene hexachlorides (BHCs) in true solution phase, colloid phase and suspended solids phase in the system from low to high was as follows: BHCsSiO2 colloid phase > BHCssuspended solids phase > BHCstrue solution phase, BHCsFe(OH)3 colloid phase > BHCstrue solution phase > BHCssuspended solids phase; the adsorption models of benzene hexachlorides with SiO2 sol and Fe(OH)3 colloid were consistent with Henry's isothermal adsorption mode and showing good linear correlation. The adsorption mechanisms of benzene hexachlorides with SiO2 sol and Fe(OH)3 colloid were studied by determining the ultraviolet spectrum and the changes in the granularity of the colloid. The result showed that the adsorption of benzene hexachlorides by the colloid was mainly physical adsorption and the stability of silicon dioxide sol was greater than that of ferric hydroxide after it adsorbed benzene hexachlorides.
