摘　　要：为给选矿废水中残余黄药的去除提供依据,分别采用自然曝晒法、漂白粉氧化法、酸化分解法、亚铁沉淀法、活性炭吸附法对配制的黄药水溶液进行了黄药降解试验,结果表明,以上诸方法均能较彻底地去除溶液中的黄药,使水中的黄原酸盐浓度达到国家排放标准。其中亚铁沉淀法、漂白粉氧化法药剂来源容易,价格便宜,工艺简单,效果好,较适合处理含黄药选矿废水。To provide the basis for the removal of the residual xanthate in the flotation effluent, xanthate degradation tests were made on the prepared xanthate solution using methods of natural exposure, oxidation by bleaching powder, acidification, settlement by ferrous sulfate and adsorption by active carbon. The results show that all the above methods can thoroughly remove the xanthate in the solution and make the concentration of xanthate in the effluent reach the state discharge standards. Of these methods, settlement by ferrous sulfate and oxidation by bleaching powder are more suitable for treating the xanthate-containing flotation effluent due to their easy-to-find agent sources, cheap price, simple technology and good effect.
