高铁酸钾氧化处理废水中邻氯苯酚的研究

摘要

Using potassium ferrate oxidation process to treat o-chlorophenol in wastewater, the influence of mass ratio of potassium ferrate to o-chlorophenol, solution pH value, and reaction time on o-chlorophenol re-moval were investigated.The results showed that,the removal rate of o-chlorophenol was proportional to the mass ratio of potassium ferrate to o-chlorophenol and reaction time. Under the condition that the initial mass concen-tration of o-chlorophenol was 25.0 mg/L, the mass ratio of potassium ferrate to o-chlorophenol was 20, the reac-tion time was 25 min,and the pH value was 9-10,the removal rate reached as high as 95.6%.%采用高铁酸钾氧化法处理废水中邻氯苯酚,考察了高铁酸钾与邻氯苯酚质量比、溶液pH值、反应时间对废水中邻氯苯酚去除率的影响.结果表明:邻氯苯酚去除率同高铁酸钾与邻氯苯酚的质量比、反应时间成正比,在废水中邻氯苯酚初始质量浓度为25.0 mg/L时,高铁酸钾与邻氯苯酚质量比为20,反应时间为25 min,溶液pH值为9~10的条件下,邻氯苯酚去除率最高可达95.6%.
