摘要：

The Cu2+, Zn2+ and Cr6+ biosorption capacity of the Streptomyces rimosus biomass pretreated with NaOH was studied in the batch mode. Under optimal experimental conditions, a biosorption capacity of 30 mg Cu2+ g(-1) biomass, 27.4 mg Zn2+ g(-1) biomass and 26.7 mg Cr6+ g(-1) biomass was obtained. The equilibrium data poorly fitted the Langmuir and Freundlich model isotherms over the whole range of initial Cu2+, Zn2+ and Cr6+ concentrations tested (0-300 mg L-1).
