| 摘 要： | 对UV/H2O2处理SFBlue制衣染料溶液的效果及其影响因素和动力学进行了研究。结果表明,UV/H2O2对SFBlue染料废液具有很好的处理效果,且在发生光助氧化降解的同时还伴随着光分解反应。UV/H2O2体系的光助氧化反应和UV体系的光分解反应均为表观一级反应,前者活化能5.17kJ/mol,指前因子0.168min-1,后者活化能16.9kJ/mol,指前因子1.04min-1。染料溶液初始pH为强碱性(pH=12)时染料降解率最大。

| Abstract: | The degradation efficiency,influencing factors and kinetics of SF Blue dye in UV/H_2O_2 system were investigated.The results show that UV/H_2O_2 has a high activity on the dye degradation.The degradation ratio at 60 min is 98% for the system containing 0.5 mL 5% H_2O_2 in 150 mL 100 mg/L dye solution.The photodecomposition reaction of the dye is accompanied with photooxidative degradation.The results also show that the photooxidative degradation of the dye in UV/H_2O_2 system is a first-order reaction with ... |
