改性高岭土掺杂TiO_(2)复合材料的制备与污水处理的研究

Study on Preparation and Sewage Treatment of Modified Kaolin Doped TiO_(2)Composites

利用改性高岭土掺杂TiO_(2)制备8种复合材料分别对Cr(VI)、Mn(VII)、Pb(II)模拟的实验室废液作为污水,通过紫外分光光度法来进行降解研究,探究8种不同的复合材料中哪种复合材料对这三种实验室废液的降解效果是最好的。实验的结果表明:10%酸改性高岭土TiO_(2)复合材料对研究的三种离子污水处理的降解效果是最好的。另外15%酸改性高岭土TiO_(2)复合材料、5%碱改性高岭土TiO_(2)复合材料、15%碱改性高岭土TiO_(2)复合材料对上述三种污水的降解效果较其他复合材料的好一些。

Modified kaolin doped TiO_(2)was used to prepare 8 kinds of composite materials.The laboratory waste liquid simulated by Cr(VI),Mn(VII)and Pb(II)was used as sewage,and the degradation study was carried out by ultraviolet spectrophotometry to explore which of 8 different composite materials had the best degradation effect on these three laboratory waste liquids.The experimental results showed that 10%acid modified kaolin TiO_(2)composite had the best degradation effect on the three kinds of ion wastewater treatment.In addition,15%acid modified kaolin TiO_(2)composite,5%alkali modified kaolin TiO_(2)composite,15%alkali modified kaolin TiO_(2)composite on the above three kinds of sewage degradation effect was better than other composite materials.
