摘要
以Cd Cl2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。
CdS/bentonite composites were prepared by using Cd Cl2 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.
