| 摘 要： | 在紫外光照射下,用过氧化氢对罗丹明B进行光催化脱色,研究了无机酸、pH值、H2O2浓度、光解时间对光催化脱色效果的影响。实验结果表明,过氧化氢光催化氧化20mg/L的RB溶液脱色的最佳条件为:用HCl调节溶液pH=2,H2O2浓度为97.63mmol/L,光解时间为15min。此时,罗丹明B脱色率可达98%以上。

| Abstract: | Photodegradation of Rhodamine B with hydrogen peroxide was investigated under ultraviolet radiation. The effects of mineral acid, pH, concentration of H2O2 and irradiation time on discoloration efficiency were studied. The optimum condition was found as follows: pH value was 2(the pH value was adjusted by HCl), the initial connection of H2O2 was 97.63 mmol/L and irradiation time 15min. The decolorization rate of Rhodamine B was beyond 98%. |
