高铁氧化去除饮用水中邻氯苯酚的研究

Removal of chlorophenol from drinking water by ferrate

采用自制的固体高铁酸钾作为氧化剂 ,研究高铁对水中微量邻氯苯酚的去除效果及主要影响因素 .结果表明 ,当水中邻氯苯酚的含量为 4mg L时 ,加入 6 0mg L的K2 FeO4 氧化处理 10min ,对邻氯苯酚的去除率可达 99.3% .取得高铁酸钾对邻氯苯酚的最佳氧化去除效果的pH范围为 9- 10 。

Utilizing the solid potassium ferrate prepared in our laboratory, the effect and impacts of removing 1\|chlorophenol from water with ferrate were stuolied. The results proved that a dose for potassium ferrate 60?mg/L can remove 99.3% of 4?mg/L 1\|chlorophenol for a 10?min oxidation duration. The optimal pH range is 9—10 for ferrate oxidizing 1\|chlorophenol. The reductive and oxidative reaction between ferrate and 1\|chlorophenol is the kinetics with approximately second order.
