摘　　要：新兴有机污染物在传统的污水处理厂处理过程中难以完全去除，如果进入到水环境中，不仅影响水质，而且对水生态系统和人类健康具有潜在的风险。高铁酸钾在水处理领域被称为环境友好型的多功能水处理剂，其氧化降解新兴有机污染物的研究备受关注。本文采用高铁酸钾（K2FeO4）氧化降解甲萘酚水溶液，研究表明，甲萘酚水溶液浓度为10mg／L时，初始pH：12—13，高铁酸钾与甲萘酚的质量比8：1，反应时间10min，温度25℃为最优反应条件，甲萘酚去除率达到89．6％左右。通过对反应产物的分析，推测甲萘酚首先被高铁酸钾氧化为1，2-萘二酚，再进一步被氧化开环生成终产物。Emerging organic contaminants were found incompletely removed in conventional wastewater treatment plants（ WWTPs ）. Wide presence of emerging organic contaminants in WWTP effluents and in receiving aquatic environments may affect water quality and pose potential risks to the aquatic ecosystem and human health. Ferrate （ VI ） （Fe（ VI ）） was regarded as an environmentally friendly oxidant in water and wastewater treatment process. The recent developments of ferrate oxidation of emerging organic contaminants were under the spotlight. Potassium ferrate （ VI ） was employed in the degradation of 1 - Naphthol solution. For 10 mg/L 1 - Naphthol solution, the optimal conditions of reaction were pH 12 - 13, 1 - Naphthol ： K2FeO4 = 8 ： 1, reaction temperature 25 ℃ and 10 min reaction time. The removal of 1 - Naphthol was 89.6%. The analysis of reaction products indicated that 1 - Naphthol was initially oxidized to 1,2 -Naphthol and then underwent ring cleavage to aliphatie compounds.
