| 摘 要： | 通过对不同锰离子浓度下三种酚在三种不同介质中的光降解情况的研究,来确定水体中的锰离子对酚类有机物的光化学降解的影响。实验结果表明,在不同条件下,不同浓度的锰离子对实验中所选的三种酚的影响有所不同。对邻硝基苯酚的光降解几乎不产生影响,对对甲基苯酚的光降解起到抑制作用,而对2,4-二硝基苯酚的光降解则起到促进作用。

| Abstract: | The photodegradation of three phenols in different mediums was studied in the presence of divalent manganese ions.The experimental results showed that under different conditions the effects of manganese on the photodegradation of phenols were different for different phenols.The presence of manganese hardly impacted on the photodegradation of o-nitrophenol,but restrained the photodegradation of p-cresol.On the contrary,the presence of manganese could accelerate the photodegradation of 2,4-dinitrophenol. |
