摘要
采用原位合成法制备出Cu2+掺杂的壳聚糖/CdS纳米复合膜,利用FTIR技术对其进行表征和分析。应用该膜在紫外光下对甲基橙进行光催化降解,探讨不同的铜掺杂量、催化剂投加量、甲基橙初始浓度、pH值等因素对甲基橙降解脱色率的影响。光催化降解过程遵循Langmuir-Hinshelwood(L-H)假一级动力学模型,相关系数均大于0.99。
Cu^2＋ -doped Cadmium sulfide （CdS） nanoparticles are prepared by in- situ synthesizing method in ehitosan hydrogel films and the resulting films are characterized and analyzed by fourier transform infrared spectmphotometer （FFIR）. The influences of Cu^2 ＋ doping content, catalyst amount, initial MO concentrations, pH on the degradation are investigated in details. The process of photocatalytic decoloLu＇ization follows a pseudo - first - order kinetics according to Langmiur- Hin shelwood （L- H） model and the correlation coefficient is larger than 0.99.
