摘要

In this study, the optimum operating condition for the removal of Cu(II) by insoluble starch xanthate (ISX) were investigated. The operating condition such as sulfur/copper molar ratio, effects of reaction time, pH, ORP, chloride and sulfate concentration for copper removal were also investigated by batch experiments. The effect of metal removal treatments were evaluated by elemental analysis (EA), X-ray powder diffraction (XRD) and Fourier transform infrared spectrumscopy (FTIR) analyses. Results from batch metal removal experiments showed that the removal of copper ion was optimized with sulfur/copper molar ratio between 1.8 and 2.5, pH between 3 and 6, and ORP between 200mV and 500mV No significant effect on copper removal efficiency was observed with chloride and sulfate concentrations below 5%. Copper ion could even be selectively removal from aqueous multi-heavy metal solutions and electroplating wastewater by ISX under the optimum operating conditions.
