高铁酸钾氧化处理水中苯酚的研究

摘要

Potassium ferrate oxidation process was used to treat phenol in water for the purpose of present-ing a high-efficient method for phenol treatment. The influences of mass ratio of potassium ferrate to phenol, so-lution pH value, and reaction time on phenol treatment effect were investigated. The test results showed that, un-der the condition that the initial mass concentration of phenol was 100 mg/L, the mass ratio of potassium ferrate to phenol was 30, the solution pH value was 9, the reaction time was 30 min, the maximum removal rate of phe-nol could reach 96.7%%采用高铁酸钾氧化法处理水中苯酚, 提供了一种高效处理水中苯酚的方法. 考察了高铁酸钾与苯酚质量比、 溶液pH值、 反应时间对水中苯酚处理效果的影响. 试验结果表明, 在苯酚初始质量浓度为100 mg/L、 高铁酸钾与苯酚质量比为30、 溶液pH值为9、 反应时间为30 min的条件下, 苯酚去除率最高可达96.7%.
