摘要：
研究了无机盐对高铁酸钾去除苯酚的影响，考察了盐的用量与苯酚的去除率之间的关系。结果表明：硫酸镁和硫酸铁都有利于高铁酸钾对苯酚的氧化去除，去除率随硫酸镁用量的增加而增大，当硫酸镁用量为0.5 g/L时，苯酚的去除率为70％，提高了40％；随着硫酸铁用量的增加，去除率先增大然后减小，当硫酸铁的用量为0.4 g/L时，苯酚的去除率最高为95％, 提高了近80％。通过对比分析得出：高铁酸钾氧化去除有机物与加入的盐类在溶液中电离后阳离子的存在状态、高铁酸根的质子化程度和高铁酸钾的稳定性等因素有关。

Abstract: The effect of inorganic salt on the phenol removal was investigated
by potassium ferrate, and the relationship between the dose of salt and the
phenol removal ratio was researched. The experimental results showed that magnesium
sulfate and ferric sulfate are good to get ride of phenol from water. When the
magnesium sulfate dose rose, the phenol removal ratio increased, but when the ferr
