摘要
以模拟可见光为光源,在自制纳米Cu2O粉末悬浮体系中,以亚甲基蓝溶液光催化降解反应为模型,研究影响亚甲基蓝光催化降解的各种因素.结果表明:对于浓度为10mg/L的亚甲基蓝溶液,当催化剂与亚甲基蓝溶液的固液比为5g/L时,太阳光辐照2h后,降解率能够达到92.46%,且加入H2O2、提高溶液pH值等方法可以显著提高亚甲基蓝的脱色降解速率.
With the model photocatalytic degradation reaction of methylene blue solution in Cu20 nanometer power suspension irradiated by visible light, this paper investigates various kinds of factors affecting photocatalytic degradation of methylene blue. The experiment results indicate that the degradation efficiency of methylene blue solution of 10 mg/L can reach 92.46% under the solar irradiation for 2 hours when the solidliquid ratio is 5g/L And such methods as H2O2 addition and increasing pH may prominently improve the discoloration and degradation rate of methylene blue.
