锰的氧化物活化过硫酸盐处理有机废水

Manganese Oxide Activated Persulfate for Treatment of Organic Wastewater

研究了一系列锰氧化物(MnO、MnO_(2)、Mn_(2)O_(3)、Mn_(3)O_(4)),并测试了锰的氧化物活化PMS对苯酚降解的效果。结果表明:活性由高到低的顺序为Mn_(2)O_(3)、MnO、Mn_(3)O_(4)、MnO_(2)。同时研究了不同因素下的处理效果,指出PMS投加量、催化剂投加量、温度与苯酚的降解效果均成正相关,且Mn_(2)O_(3)重复使用效果较好,可多次循环利用,是高效环保的催化材料。

A series of manganese oxides(MnO,MnO_(2),Mn_(2)O_(3),Mn_(3)O_(4))were studied,and the degradation effect of manganese oxide activated PMS on phenol was tested.The order of activity was determined as follows:Mn_(2)O_(3)>MnO>Mn_(3)O_(4)>MnO_(2).At the same time,the treatment effects under different factors were studied.It was concluded that the dosage of PMS,the dosage of catalyst and temperature were positively correlated with the degradation effect of phenol,and the reuse effect was good.It could be recycled for many times.It is an efficient and environmental friendly catalytic material.
