无机盐高铁酸钾去除微污染水中苯胺的研究

以苯胺为代表性污染物,借用全自动六联混凝试验搅拌机,实验研究了自制的高铁酸钾对微污染水中难降解有机物的去除功效、影响因素及其去除作用机制。结果表明,高铁酸钾对苯胺具有比较好的去除作用,但受高铁酸钾的投加量、反应时间、体系的pH、苯胺初始浓度等的影响,其最佳反应时间为30 min,pH=9.0~9.5。通过高铁酸钾作用过程中氧化与絮凝作用的定量研究发现,高铁酸钾去除苯胺主要是通过氧化作用实现的。

Study on removal of aniline by potassium ferrate

Utilizing the solid potassium ferrate prepared in our laboratory,the effect and impacts of removal aniline from water with potassium ferrate were studied.The results indicated that the rate of potassium ferrate removing aniline depends on the value of pH,potassium ferrate concentration,and reacting time.The optimal pH range is 9.0～9.5,and the optimal react time is 30 min,for potassium ferrate removing aniline,and the potassium ferrate concentration is corresponding with the initial aniline concentration.
