【摘要】 以阳离子树脂为载体,通过浸渍法,制备了一种新型Fe-H-732载铁树脂催化剂。基于单因素实验,研究了制备条件对Fe-H-732催化性能的影响规律。利用Fe-H-732活化过硫酸盐（PS）去除皂黄（MYG）,考察了其催化性能及其降解机制。结果表明:在FeSO₄溶液浓度为0.05mol·L^-1时,Fe-H-732对MYG去除率最高;Fe-H-732/PS对MYG的去除率比FeSO₄均相催化剂高71.8%,Fe-H-732显示出优异的催化性能;在硫酸根(SO₄^·-)和羟基自由基（OH^·）的作用下,MYG最终被分解成CO₂、H₂O和无机盐;Fe-H-732在重复利用5次后,对MYG的去除率仍高于97.5%,这表明Fe-H-732具有较好的稳定性。本研究结果可为高效低成本染料废水净化催化剂的合成提供参考。更多还原

【Abstract】 A novel Fe-H-732 was prepared by impregnation using a cationic resin as a support. The effect of the preparation conditions on the catalytic properties of Fe-H-732 has been studied based on singlefactor 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 removal rate of Fe-H-732/PS is 71.8% higher than that of FeSO₄, which indicated that Fe-H-732 exhibits excellent catalytic properties. MYG is eventually decomposed into CO₂, H₂O and inorganic salts, under the attack of sulfate(SO₄^·-) and hydroxyl radical（OH^·）. The MYG removal rate of Fe-H-732 remained above97.5% 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.更多还原
