表面活性剂对乙烯菌核利光解的影响

Effects of surfactants on photolysis of vinclozolin

研究了6种表面活性剂对乙烯菌核利在液相和固相表面光解的影响。结果表明,高压汞灯下,表面活性剂对乙烯菌核利液相光解的光猝灭效应随其添加浓度的不同而存在显著差异;但在玻片表面上,不同添加浓度对光猝灭效应的影响差异较小。太阳光下,SLS、SLBS、CTAB和S-20对乙烯菌核利的液相光解表现为光敏化效应;但在玻片上,只有SDS表现为光敏化效应。

The effects of 6 kinds of surfactants on photolysis of vinclozolin in redistilled water and on glass surface under high pressure mercury lamp and sun light were studied. Results showed that there were significant differences of effects on photolysis of vinclozolin in redistilled water under high pressure mercury lamp, as surfactants were fortified with various concentrations. But on glass surface, photoquenching effect of surfactants on photolysis of vinclozolin changed in a narrow range with various fortification concentrations. Under sun light, SLS, SLBS, CTAB and S-20 showed photosensitizing effect on photolysis of vinclozolin in redistilled water, but only SDS showed photosensitizing effect on glass surface.
