lignosulphonic acid

The effect of illumination of ozonic and no-ozonic ultraviolet bactericidal lamp was studied on the decolorization rate of methyl orange dye solution.

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。

Effect of Two Kind of Ultraviolet Bactericidal Lamp Illumination on Decolorization of Methyl Orange

两种紫外线杀菌灯对甲基橙染料的脱色作用

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.

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%。
