中文摘要: 通过溶剂热法制备了CuInS2可见光响应型材料,借助SEM和XRD对材料进行表征分析。探究了不同溶液pH、反应时间、CuInS2浓度、U(Ⅵ)初始浓度对CuInS2光催化还原U(Ⅵ)性能的影响。结果表明,CuInS2具有良好的光催化性能,在溶液pH=5.5、U(Ⅵ)初始浓度10.0 mg/L、CuInS2浓度0.8 g/L时,CuInS2材料对溶液中U(Ⅵ)的去除效果最佳,去除率为87.81%,去除量为12.13 mg/g。

Abstract:CuInS2 visible light-responsive photocatalysts was prepared by Solvothermal method characterized with SEM and XRD. Effects of pH value of solution, reaction time, CuInS2 concentration, and U(Ⅵ) initial concentration on photocatalytic reduction of U(Ⅵ) by CuInS2 were explored. The results show that CuInS2 has positive effect on U(Ⅵ), and removal rate and adsorption capacity of U(Ⅵ) is 87.81% and 12.13 mg/g respectively under the conditions including pH value of solution of 5.5, initial concentration of U(Ⅵ) of 10.0 mg/L, and CuInS2 concentration of 0.8 g/L.
