Abstract

The effects of pH, temperature, single and dual metal ion concentrations, initial Planococcus biomass quantities, and desorption agents on the uptake of cadmium (II) and nickel (II) were measured using atomic absorption spectrophotometry. To show surface adsorption of bacteria, SEM-EDX and FTIR analysis were done before and after metals adsorption. The maximum biosorption capacity of Planococcus sp. for single and binary ion was determined to be 0.67 and 0.48 mmol/g for cadmium (II) and 0.58 and 0.47 mmol/g for nickel (II), respectively. The correlation coefficient for the second-order kinetic model was 0.993. The Langmuir and Freundlich isotherm models were also applied to the equilibrium of system and data were better fitted with the Langmuir isotherm
