摘要
研究了几种阳离子和pH值对纳米二氧化钛光催化降解斯蒂酚酸的影响。结果表明 :在实验条件下 ,Fe3+ 、Cu2 + 、Zn2 + 3种阳离子使光催化的效果增强 ,Mn2 + 对光催化产生一定的抑制作用 ,水体pH值高于或低于二氧化钛等电点时对光催化降解有促进作用。在实验研究的基础上 。
Exeriments are carried out to study the effects of several positive ions on the photocatalytic degradation of 2,4,6 trinitroresorcinol (TNR).The result shows that under the experimental conditions the effet of photocatalysis can be reinforced by the addition of Fe 3+ ,Cu 2+ ,Zn 2+ and the rise or descend of pH value.On the contrary,Mn 2+ just restrains it.Also the influence mechanism is studied.
