Abstract

Abstract

Adsorption behavior of trichloroethylene on the simulated orano-mineral complex and the mixture of mineral and humic acid were comparatively studied with batch technique. The results show that sorption capacity of trichloroethylene by kaolinite and quartz sand is quite small compared to that of the humic acid. Trichloroethylene sorption to the simulated organo-minerals exhibits linear isotherm and K_oc decreases with the increase of the humic acid loading, being less than that of the pure humic acid. The interaction of humic acid and simulated minerals affects the sorption of trichloroethylene. Based on the analysis of conformation of the humic acid in the complexes, a model of organo-mineral is generalized to explain the results well.
