摘要
近年来,随着纺织业的迅速发展,染料废水已成为水体的重要污染源之一,废水处理问题引起了人们的广泛关注.本文利用氯化镉和硫化钠为原料,利用水热合成方法制备了立方CdS纳米材料.对样品进行了X射线粉末衍射(XRD)和透射电镜(TEM)测试,分析了CdS样品对罗丹明B溶液的光催化降解效果.实验结果表明,聚乙二醇的加入影响着硫化镉的分散程度和形貌,进而影响硫化镉的光催化活性;降解体系的pH值对罗丹明B的降解效果有较大影响.
In recent years,with the rapid development of textile industry,dye wastewater had become one of the pollution source of waters,and its treatment become a thorny problem attracting the worldwide attention.Using CdCl2 and Na2S as raw materials,the cubic CdS nanomaterial were prepared by a facial hydrothermal method and charaterized by XRD and SEM.The photocatalytic degradation effect of CdS to Rhodamine B solution was studied.The result exhibited dose of polyethylene glycol had effect on the dispersion degree,morphology and then photocatalytic performance of CdS samples.The pH value of degradation system had a great influence on the degradation efficiency of Rhodamine B solution.
