摘要
本文提出用金属氧化物复合体系ZnO-CuO半导体光催化降解PVA水溶液,有较好的效果。研究了在该体系下各因素对PVA光降解的影响,确定了较好的实验条件,并发现空气也是一个重要因素。
A compound metal oxide (ZnO-CuO) system used for photo-catalytic degradation of PVA is provided. It is found that the system has ability to degradate PVA quickly and to remove COD effectively in the presence of oxygen (in the air) with irradiation of UV rays. The various factors to influence the photo-catalytic degradation of PVA have been studied and optimum test conditions have been selected.
