Abstract

Biosorption is the method of removing heavy metal from the aqueous solution. Oscillatoria sp microalgae were used to adsorb copper ions in this study. The maximum biosorption capacity was obtained 4.9 mg/g at pH of 9 with an efficiency of 99%. The algae dosage in 0.1 g gave the maximum capacity of 12.33 mg/g. The maximum contact time occurred at 60 minutes with an adsorption capacity of 19.87 mg/g. Adsorption Cu2+ by microalgae Oscillatoria sp followed by the Langmuir and Freundlich isotherms. According to the Langmuir models the value of qm is 217.39 mg/g , KL = 8.8 x10-4 L/mg, and R2 = 0.9999. The Freundlich model showed the coefficient correlation R2 = 1, 1/n = 1.0162, and Kf = 5.39. The model of pseudo-second-order with qe = 4.98 mg/g, k2 = 81.38 g mg-1 h-1, and R2 = 1.
