Research on the sorption process of copper metal (Cu2+) from artificial electroplating wastes using a biotechnology approach was studied using beads biosorbent of mixed culture microalgae Chlorella vulgaris, Chlorococcum sp., and Scenedesmus obliquus conducted in batch culture to determine the highest efficiency of Cu2+ adsorption as an effort to control Cu2+ pollution from the environment. Biosorbent is made into beads by mixing 0, 5 gr (dead biomass)/gr (Na-alginate polymer). The beads biosorbent of these microalgae are contacted with Cu2+ in the pH range 4-6 and contact time 0-180 minutes. The highest sorption efficiency of Cu2+ is 92% obtained at pH 4, 120 minutes' contact time, in temperature of 25 ºC, and with an initial waste concentration of 25 mg/L. The sorption process of this research follows Langmuir Isotherm with R2 value of 0, 9991. It is proven that beads biosorbent of mixed culture microalgae can be used as an environmental-friendly solution to control Cu2+ pollution in the environment.
