摘　　要：利用气相色谱质谱联用(GC-MS)技术测定了酯-105、戊基黄原酸钾、铜抑制剂在矿山环境中降解所产生的二次污染物的成分。结果表明,在模拟的尾矿库条件下,3种选矿药剂会产生COS、CS2、醇类、醛类、酮类、腈类一系列小分子污染物,这些小分子物质是比选矿药剂本身更严重的二次污染物。The secondary pollutants photo degraded fromester- 105 ,potassium amylxanthate and inhibitor of Cu are analyzed using GC-MS. Under the imitating condition of tailings pond the results show that three kinds of processing agents in the experiment may be degraded and produced a series of pollutants with small molecule, such as COS, CS2, alcohols, alde- hydes,ketones, nitriles etc. These small molecules are more serious than the processing agents themselves.
