摘要
本文选取选矿药剂酯-105为研究对象,将其和混合硫化矿、水装入石英瓶中,在自然光下照射19d,而后抽取顶空气体进行GC-MS测定,发现有丙烯腈等二次污染物。降解产物中丙烯腈含量最高,对其进行定量分析,发现已远远超出国家规定的含量,应引起关注。
The degradation process of ester - 105 mixed with sulfide ore and water in quartz photies reactor under sun light exposure for 19 days is investigated. The reacted gas taken to the top air is determined by GC-MS. The results show that the floatation reagent can release the secondary pollutants such as acrylonitrile. The highest content among degradation components is acrylonitrile, which has far exceeded the content listed in Chinese national standard by quantitative analysis. More concern should be taken to this problem.
