Research on the Treatment of Xanthate Wastewater by flocculation Process

摘要

As the widely used collector, environmental pollution and toxicity of xanthates have got more and more concerns. In the present work, the flocculation process had been used to treat xanthate wastewater. The results showed that Al_2(SO_4)_3 was the optimal flocculant. At the conditions of dosage of 0.1mol·L~(-1) Al_2(SO_4)_3 0.5 mL, the initial pH 6.5, vibrating time 90 min and settling time 120 min, sodium isobutyl xanthate was removed nearly up to 100%.
