| 摘 要： | 对南墅石墨矿尾矿进行回收,得到天然金红石精矿。通过粉碎、分级等手段制备了天然金红石光催化材料。用制备的天然金红石光催化材料处理含偶氮染料工业废水。结果表明:在紫外光照射条件下处理4 h后,其对偶氮染料工业废水的脱色率达到88.37%。对比实验表明其对偶氮染料的作用既有吸附,也有降解,说明该天然金红石光催化材料有一定的光催化活性。

| Abstract: | Natural rutile photocatalyst was prepared with the method of grinding and sizing.This photocatalyst was used to treat industrial wastewater containing azo dye.It shows that the decoloration rate of the azo dye industrial wastewater can reach 88.37% in the effect of natural rutile photocatalyst after irradiate by the UV radiation for 4 h.Contrast experiment shows that the photocatalyst have not only sorption but also photocatalysis on the azo dye industrial wastewater. |
