ABSTRACT
The study describes the sorption of living ureolytic mixed culture (UMC) to remove Cu(II) from aqueous solution under various conditions. The effects of various parameters such as optimum biomass, contact time, and Cu(II) concentrations on Cu(II) removal efficiency were investigated. The process was investigated using concentrations of Cu(II) ions ranging from 1 to 200 mg/L in equilibrium batch tests for Langmiur, D-R, and Freundlich isotherm models. The maximum removal efficiency of 99% was obtained a 1 g/L solid-to-liquid ratio with 1-min contact time for 100 mg/L initial concentration of Cu(II).
