摘　　要：以产生臭氧和不产生臭氧两种紫外线杀菌灯为光源,以甲基橙染料为对象,染料脱色率为指标,研究了两种光源对甲基橙的脱色作用.结果表明:甲基橙在产生臭氧和不产生臭氧两种光源照射下脱色率不同,光照3h后甲基橙脱色率分别为79.1%和7.9%.造成高脱色率的因素不是紫外线杀菌灯产生的臭氧,可能是紫外线杀菌灯产生的真空紫外线对甲基橙作用的结果.The effect of illumination of ozonic and no-ozonic ultraviolet bactericidal lamp was studied on the decolorization rate of methyl orange dye solution. The experiment results show that the decolorization efficiency of methyl orange dye solution was 79.1% and 7.9% respectively under ozonic and no-ozonic ultraviolet bactericidal lamp illumination when treating time was 3 hours. It indicated that the higher decolorization efficiency probably not due to ozone produced by UV lamp but vacuum UV rays from UV lamp.
