摘要

以CdCl

和硫代乙酰胺为反应物

通过湿化学法合成CdS/膨润土复合材料

采用X射线衍射(XRD)、红外光谱(FTIR)以及紫外可见光谱(UV-Vis)等分析技术对其结构及光学性能进行表征。以罗丹明B和亚甲基蓝为目标污染物

考察了CdS/膨润土复合材料对有机染料的降解性能。结果表明:在罗丹明B和亚甲基蓝的初始浓度为20 mg/L 时

光照3 h后

CdS/膨润土对它们的降解率分别为80.6%和88.3%

优于CdS及膨润土原土催化剂。

Abstract

CdS/bentonite composites were prepared by using CdCl

and thioacetamide as reactants. The obtained samples were characterized by X-ray diffraction (XRD)

Fourier transform infrared spectra (FTIR) and ultraviolet-visible spectra (UV-Vis). The effect of CdS/bentonite composites on photocatalysis degradation of organic dyes (such as rhodamine B and methylene blue) was investigated in detail. Under irradiation for 3 h

it was found that 80.6% (for rhodamine B) and 88.3% (for methylene blue) of degradation rates were achieved when the dye initial concentration was 20 mg/L. The performance of CdS/bentonite composites catalyst is superior to pure CdS or bentonite.
