摘要： 本文通过长春市南湖水中生物膜优势菌种胞外蛋白吸附Pb2+和Cd2+的实验, 研究了胞外蛋白吸附重金属的规律.

关键词: 生物膜, 胞外蛋白质, 吸附, Pb2+, Cd2+

Abstract: The adsorption of Pb2+ and Cd2+ on the extracellular protein of natural biofilm was investigated. The extracellular protein was obtained from the extracellular polymers of superiority bacteria of natural biofilm cultivated in South Lake of Changchun. The results showed that both Langmuir and Freundlich isotherm equations could be used to describe the thermodynamics adsorption processes of Pb2+ and Cd2+ on the extracellular protein.

Key words: Biofilm, Extracellular protein, Adsorption, Pb2+, Cd2+
