| Abstract: | The adsorption of three kinds of heavy metals Mn, Cd and Pb by extracellular polymers was investigated. The extracellular polymers were obtained from superiority bacteria in Changchun South Lake. The results show that both the Langmuir and the Freundlich isotherm equations could describe the course of the adsorption of the three metals on the extracellular polymers. The existence of Mn in extracellular polymers affected the adsorption of Pb more seriously than that of
Cd. |
