摘要
研究了高铁酸盐的水溶液稳定性 ,证明水中的H+ 和Fe3+ 对高铁的分解具有明显的催化作用 ,当水的pH低于 5时 ,FeO4 2 -将迅速分解 ,而少量的Fe3 + 也将导致FeO4 2 -的诱发分解效应 .利用H+ 和Fe3+ 对高铁的催化分解作用 ,可明显提高K2 FeO4 对水中污染物的去除效果 ,在 pH =4条件下加入K2 FeO4 和按质量比FeCl3∶K2 FeC13=5加入FeCl3,对水中富里酸(FA)和氨氮 (NH3 N)的去除率均可提高 10
The aquatic stability of ferrate and its application in water purification were studied. The results showed that H + and Fe 3+ accelerate the decomposition of FeO 4 2- . In the condition of pH below 5, FeO 4 2- decomposed immediately. As well, a little amount of Fe 3+ resulted in FeO 4 2- decomposition quickly. Applying the affect of H + and Fe 3+ catalyzing FeO 4 2- decomposition, the effect of pollutants removal from water by ferrate can be improved effectively. In ...
