摘要/Abstract

摘要： 研究了长春市伊通河天然水体中优势菌种非活性细胞对Pb^２＋和Cd^２＋的吸附及其影响因素. 发现细菌生物量对非活性细胞吸附Pb^２＋的影响比对Cd^２＋的影响大；细菌对Pb^２＋的吸附在pH=4.5时吸附量最大，而对Cd^２＋的吸附在pH=6.0时吸附量最大；细菌对Pb^２＋和Cd^２＋的吸附在30 ℃最大；当Pb^２＋和Cd２＋共存时， Pb^２＋对细菌吸附Cd^２＋的影响不显著，细菌对Pb２＋的吸附量随Cd^２＋浓度的增大而减少.

Abstract: The biosorption of Cd^２＋ and Pb^２＋ onto the dominant dead bacteria in the Yitong River and the effects of temperature, initial pH, initial metal ions and bacteria biomass on the biosorption were investigated. The results show that bacteria biomass had more influence on Pb^２＋ biosorption than on Cd^２＋ biosorption. The bacteria show the highest Pb^２＋ uptake capacities at an initial pH value of 4.5, and show the highest Cd^２＋ uptake capacities at an initial pH value of 6.0. The bacteria exhibited the highest Pb^２＋ and Cd^２＋ uptake capacities at 30 ℃. The concomitant Pb^２＋ had no considerable effect on the biosorption of Cd^２＋, and the concomitant Cd^２＋ had a considerable effect on the biosorption of Pb^２＋.

Key words: dominant bacteria, Cd^２＋, Pb^２＋, biosorption amount, concomitant metal ion
