载铁树脂催化剂高效活化过硫酸盐降解皂黄的研究
Studies of the Degradation of the Metanil Yellow by Fe/resin Catalyst Efficiently Activated Persulfate
摘要
Abstract
A novel Fe-H-732 was prepared by impregnation using a cationic resin as a support.The ef-fect of the preparation conditions on the catalytic properties of Fe-H-732 has been studied based on single-factor experiments.The Fe-H-732 was used to activate persulfate(PS)to remove Metanil Yellow(MYG),and its catalytic capacity and degradation mechanism were investigated.The results show that Fe-H-732 has the highest MYG removal rate when the concentration of FeSO4 solution is 0.05 mol·L-1.The MYG remov-al rate of Fe-H-732/PS is 71.8%higher than that of FeSO4,which indicated that Fe-H-732 exhibits excel-lent catalytic properties.MYG is eventually decomposed into CO2,H2O and inorganic salts,under the at-tack of sulfate(SO4·-)and hydroxyl radical(OH·).The MYG removal rate of Fe-H-732 remained above 97.5%after five recycling runs,indicating the great stability of Fe-H-732.The results of this study can serve as a reference for the synthesis of high-efficiency and low-cost dye wastewater purification catalysts.关键词
