摘　　要：研究矿山常用药剂戊基黄原酸钾和酯-105在不同条件下的降解过程。结果表明,在模拟尾矿库条件下,所用药剂均产生CS2,而且CS2向COS转化。药剂在降解的过程中会产生乙醇、乙醛、丙酮、乙腈、丙腈、异丁醇、戊醇等一系列小分子二次污染物。这些二次污染物是水溶性的重金属络合剂,将影响重金属的赋存在状态与迁移规律。The degradation process of potassium amyl xanthate and ester-105 as the common reagents used in mines under different conditions is investigated. It is indicated by the experiments that the adopted reagents in the experiment may be degraded and the CS2 is released, further more, CS2 may be converted to COS, under the imitating condition of the tailings pool. A series of secondary pollutants with small molecule are produced from these reagents, such as ethanol, aldehyde, acetone, acetonitrile, propionitrile, isobutanol, amyl alcohol, et al. The depositing forms and the law of migration of heavy metals in the tailings pool would be influenced by these secondary pollutants because they are the water-soluble chelating agents of heavy metals.
