Abstract

Abstract: The adsorption of natural surface coatings, developed in the Nanhu Lake(Ch angchun, China), towards Cd was studied to determine the effects of the amounts of Fe oxides in surface coatings on Cd adsorption and the dyn amics and thermodynamic characteristics of Cd adsorption. The results indicate that the amounts of Fe oxides influence Cd adsorption to natural surface coating s greatly.

Key words: natural water surface coatings, Fe oxides, cadmium, adsorption
