摘　　要：黄药(黄原酸盐)是目前金属矿山浮选工艺中应用最广的硫化矿捕收剂.经浮选后的该类选矿废水中残余一定量的黄药,若不处理易造成环境污染.研究了用氢氧自由基处理某选矿残余的黄药废水,考查了pH值、H2O2和Fe2+浓度对黄药去除率的影响.结果表明,在H2O2/COD质量浓度比为1.5,Fe2+/COD质量浓度比为0.25,初始pH值为3的条件下,反应90min后黄药的去除率可达94.7%,废水可达标排放.Xanthate is generally used as collector in flotation process of metal mining.Without treatment,the floatation wastewater is easy to cause environment pollution due to its containing remnant xanthate medicament.The treatment of xanthate in a certain mineral processing wastewater by hydroxyl radical is studied in terms of the effects of pH value,H202 and Fe2+ concentration on the removal efficiency of xanthate.The results show that the removal of xanthate attains up to 94.7%,when the initial pH value is 3,with optimal parameters of 1.5 and 0.25 for H2O2/COD(w/w) and Fe2+/COD(w/w),respectively.The effluent quality meets the national standard of wastewater discharge.
