摘　　要：分别使用酸化分解法、铁盐混凝沉降法、活性炭吸附法、漂白粉氧化法和自然曝晒法来去除水中微量的丁基黄药,试验结果表明,对于500 mL浓度为20 mg/L的丁基黄药废水,添加1%盐酸0.3 mL、硫酸亚铁900 mg、活性炭500 mg和漂白粉25 mg可在处理2 h的情况下使黄药去除率达到100%。Acid decomposition method,iron salt coagulation sedimentation method,activated carbon adsorption method,bleaching powder oxidation method,and natural exposure method were used to remove trace amounts of butyl xanthate in waste water.The experimental results showed that for 500 mL butyl xanthate wastewater with a concentration of 20 mg/L,the addition of 1%hydrochloric acid 0.3 mL,ferrous sulfate 900 mg,activated carbon 500 mg and bleaching powder 25 mg could make the xanthate removal rate reach 100%under the condition of treatment for 2 hours.
