Abstract :The aim of this study is to determine the adsorption behavior of borax sludge for removal of copper from industrial wastewater. The borax sludge was generated during borax production and used for treatment of wastewater of metal coating process. The parameters of pH, concentration and contact time were investigated in batch experiments to determine the efficiency of adsorption. Inductively Coupled Plasma-Optical Emission Spectrometer insert ignore into journalissuearticles values(ICP-OES); was used to calculate the reduced amount of Cu insert ignore into journalissuearticles values(II);. The results were applied to various kinetic models and adsorption isotherms. The pseudo second order model was successful to fit the adsorption process in the kinetic study because the regression coefficient values insert ignore into journalissuearticles values(R 2 ); were changed between 0.9995 and 0.9978. Langmuir insert ignore into journalissuearticles values(R 2 =0.9985); and Temkin insert ignore into journalissuearticles values(R 2 =0.9985); isotherms models were the best to explain the process.
