摘要
本实验以高铁酸钾为水处理剂,对其在废水中的硝基苯的去除进行了研究,考察了高铁酸钾的用量、pH值、反应时间及硝基苯的初始浓度四个影响因素对硝基苯去除率的影响,最终确定了高铁酸钾去除硝基苯的最佳反应条件为:初始pH值为9,高铁酸钾与硝基苯的摩尔比为10:1,反应时间30 min,初始浓度小于254.5mg/L时,硝基苯的去除率最佳,达到60.2%。
Nitrobenzene in wastewater was removed by using potassium fen-ate. The effects of potassium ferrate dosage, pH, reaction time and original concentration of nitrobenzene on removal efficiency of nitrobenzene were investigated. It was found that the effect lied on the dosage of potassium ferrate, pH value, reaction time and original concentration , and the best condition of the reaction was：the beginning pH value was 9,the tool ratio of potassium ferrate and nitrobenzene was 10：1 ,the reaction time lasted 30rain, and original concentration is below 254.5mg/L when the highest removal efficiency of nitrobenzene reached 60. 2%.
