光解法处理有机汞污水的探索
- AN INVESTIGATION ON PHOTOLYTIC TREATMENT OF ORGANOMERCURY POLLUTED WATER
- 摘要：本文用自由基捕捉剂亚硝基叔丁烷（MNP）,2,3,5,6-四甲基亚硝基苯（ND）及苯亚甲基叔丁基氮氧化物（PBN）与ESR相结合的方法研究了二苯基汞（DPM）在胶束中光解产生的活泼自由基。结果表明:（1）在含有表面活性剂的水体系中,DPM光解产生苯基自由、基并可被MNP捕获;（2）在含有表面活性剂的某些有机溶剂RH中,DPM光解不仅产生自由基C6H5,并且随溶剂不同,C6H5可夺取溶剂RH上的活泼氢而产生次级自由基R,它们均能被ND或PBN捕获。
- Abstract：The active free radicals formed during the photolysis of diphenyl-mercury (DPM) in micellar solution have been examined by ESRspectro-scopy and spin trapping technique. The results showed that:1. In aqueous media containing surfactants, phenyl radical could be formed during the photolysis of DPM and trapped by methyl nitrosopro-pane (MNP).2. In some organic solvent RH containing surfactants, not only the primary radical C6H5 ,but also the secondary radicals R were produced during the photolysis of DPM.
