| Abstract: | A preparation of straw xanthates using chromium hydrxide reaction effluent from metal chromium industry as alkali source is reported in this paper.The removal of zinc from wastewater with straw xanthate was investigated.The process was studied taking into account such parmeters as:pH of water,xantate dosage and reaction time.The residual concentrations of zinc after treatment can be reduced to values of less than 1.0 mg/L |
