Abstract

The experiment was carried out on the stability of heavy metals with the high concentration of heavy metal solution, which was prepared by absorbing bentonite and bentonite. The results show that after adding a certain amount of adsorption material in heavy metal solution, bentonite, concavo convex rod soil and heavy metal ion solution after reaction, on Pb and Cd adsorption rate can reach more than 80%; scanning electron microscope results show that a large amount of metal ions adsorbed on the surface of the adsorption material. Further with the aid of X ray diffraction analysis, Bentonite, attapulgite and heavy metal ions to generate CdCO3, PbCO3 and PbSiO3 and other new materials. The experimental results show that bentonite and attapulgite can be used in the treatment of heavy metal pollution.
