采用液-液界面反应成功制备了花状CuS自组装微球.用X射线衍射分析仪、扫描电子显微镜、能量散射型X射线荧光光谱仪、紫外可见分光光度仪对该球进行表征,研究了其对苯酚类物质光催化降解性能,探讨了光照时间、苯酚类物质初始浓度、溶液pH 值、CuS投加量、H2O2加入体积对光催化性能的影响.结果表明,产物是粒径为600~900 nm的花状CuS微球,该球对苯酚类物质具有很好的光催化降解效果,符合 Langmuir-Hin-shelwood一级动力学模型,在最优条件下,苯酚的降解率可达68.54%,邻苯二酚的降解率可达85.31%,间苯二酚的降解率可达79.56%,对苯二酚的降解率可达94.99%.

Self-assembled CuS flower-like microspheres were successfully prepared by liquid-liquid interfacial reaction. The sample was analyzed by XRD, SEM, EDX and UV-Vis. The influence factors for degradation including the time of illumination, the concentration of solution, the pH, the dosage of CuS and the volume of H2O2 on the photocatalytic activity were studied. The results showed that the products were flower-like microspheres with an average diameter of 600-900 nm. The sample had good degradation for phenol, and the experimental data was describ...
