UV-Fenton试剂降解水中苯酚的研究

采用UV—Fenton法降解苯酚溶液，研究其对苯酚光催化降解过程的影响因素。考察了光照时间、苯酚初始浓度、H2O2和Fe^2＋用量、溶液pH值等对苯酚光催化降解的影响。结果表明，常温下苯酚初始浓度为300mg·L^-1时，在光照时间为10min，H2O2浓度为20mmol·L^-1，Fe^2＋浓度为3．6mmol·L^-1，pH值为4时，苯酚降解率可达98．37％。

Study on phenol degradation in water with UV-Fenton reagent

The phenol solution is treated with UV-Fenton tO study the factors influencing the degradation process such as the UV irradiation time, the initial concentration of phenol solution, H2O2 and Fe^2＋ quantity, and Fenton reagent pH value etc. The experimental results indicate that the degradation rate can reach to 98. 37% in the following conditions, initial phenol concentration 300 mg · L^-1 , irradiation time 10 min, the concentrations of H2O2 and Fe^2＋ are 20 mmol· L^-1 and 3.6 mmol· L^-1 respectively, and pH value 4.
