Abstract
This paper investigates into the adsorption of cadmium and lead by dead bacteria cell in Nanhu Lake, Changchun City. Results show that the course of adsorption of the two metals complies with both the Langmuir and the Freundlich isotherm equations. In terms of the competence of adsorption between the two metals, the presence of cadmium affects the adsorption of lead more remarkably than does lead to cadmium.
