高铁酸钾氧化降解水中的苯酚
Oxidative Degradation of Phenol in Water with Potassium Ferrate
【摘要】 以自制的固体K2FeO4作为氧化剂对水中的苯酚进行氧化降解。在苯酚初始浓度为0.10 mmol/L、溶液pH为9、反应时间为30 min、n(K2FeO4)∶n(苯酚)为15的条件下,苯酚去除率可达99.8%。反应过程中,K2FeO4的强氧化作用与其产物Fe(OH)3的絮凝作用产生协同效应,提高了苯酚的降解效果。表观反应动力学研究结果表明K2FeO4与苯酚的反应符合二级反应动力学原理。
【Abstract】 Phenol in water was oxidized with self-made solid K2FeO4 as oxidant.Under the conditions of initial phenol concentration 0.10 mmol/L,solution pH 9,reaction time 30 min,n(K2FeO4) ∶ n(phenol)=15,the phenol removal rate is 99.8%.In the reaction process,the strong oxidation by K2FeO4 and the flocculation by the product Fe(OH)3 have the synergistic effect on the degradation of phenol.The results of apparent reaction kinetics research show that the reaction between K2FeO4 and phenol follows the second order kinetics law.
