| Abstract: |
| 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 ... |
