以实验室自制高铁酸钾(K_2FeO_4)为氧化剂,对水中邻氯苯酚(OCP)的氧化条件进行了研究。结果表明,当高铁酸钾的投加量与邻氯苯酚质量比为5:1时,邻氯苯酚去除率达到60%;当投加氧化剂后反应时间为10 min时,邻氯苯酚去除率达到60%;在反应温度为30℃时,邻氯苯酚有效去除率达到60%;在反应体系pH值为9～10时,邻氯苯酚去除率为65%。反应体系中pH值9～10,反应时间10 min,温度30℃,氧化剂投加量质量比5:1,为K_2FeO_4去除水中邻氯苯酚的最佳试验条件。
Oxidation conditions of o-chlorophenol (OCP) in water were studied using potassium ferrate (K 2 FeO 4) as oxidant in laboratory. The results showed that when the mass ratio of potassium ferrate and o-chlorophenol was 5: 1, the removal rate of o-chlorophenol reached 60%. When the reaction time was 10 min, the removal rate of o-chlorophenol reached 60%. At the reaction temperature of 30 ℃, the effective removal rate of o-chlorophenol reached 60%. The o-chlorophenol removal rate was 65% when the reaction system pH was 9-10. The reaction conditions pH 9 ~ 10, reaction time 10 min, temperature 30 ℃, the mass ratio of oxidant to add 5: 1, K_2FeO_4 is the best experimental conditions for the removal of o-chlorophenol in water.
