| 摘 要： | 采用离子色谱分析方法研究了UV/过氧单硫酸盐(UV/PMS)体系中溴酸盐的生成规律以及控制方法。实验结果表明:溴离子初始浓度为20μmol·L-1,PMS投量为500μmol·L-1,反应15 min时溴酸盐的浓度为4.96μmol·L-1。溴酸盐浓度随着PMS投量的增加而增加,随着溴离子初始浓度的增加而降低。而向UV/PMS体系中投加过氧化氢,能够明显地抑制溴酸盐的生成。为基于硫酸自由基的高级氧化工艺处理含溴水体时溴酸盐的生成和控制提供参考。

| Abstract: | The production and control of bromate in the UV/PMS system were studied by the means of ion chromatography analysis.Results showed that bromate was produced and the concentration of reached 4.96 μmol·L-1 by 15 min at PMS dose of 500 μmol·L-1 and bromide concentration of 20 μmol·L-1.The concentration of bromate increased with the dose of PMS,but decreased with the increase of initial concentration of bromide.Finally,it was found that the addition of hydrogen peroxide could reduce the production of bromate efficiently.The conclusions would provide a reference to control the production of bromate for the application of UV/PMS in the treatment of bromide-containing water. |
