In an effort to further improve the catalytic efficiency of non-homogeneous Fenton catalysts for the catalytic degradation of organic dyes like methylene blue,methyl orange,and rhodamine B,Fe/Cu/molecular sieve composites were made using an impregnation technique.The impregnation process was used to create the composites.After determining the ideal reaction circumstances for the degradation system and optimizing the preparation process's main process parameters,the degradation mechanism was examined.The findings demonstrated that,under ideal reaction conditions,the Fe/Cu/mo-lecular sieve composite reacted for 25 minutes,degrading methylene blue at a rate of 96.80%while also having a superior degrading effect on a range of organic dye solutions.Therefore,there are some potential uses for the catalyst in the field of treating wastewater containing industrial organic dyes.
