摘　　要：将铁酞菁(Fe Pc)和钴酞菁(Co Pc)分别负载到棉纤维上,制备了催化功能纤维(Fe Pc/F、Co Pc/F),并研究其对四种偶氮染料的催化脱色性能。结果表明,H2O2的存在,能有效提高催化功能纤维对这四种染料的脱色率。中性和弱碱性条件下,催化功能纤维能有效氧化降解活性艳红3BSN和酸性黄G。Iron phthalocyanine （FePc） and cobalt phthalocyanine （CoPc） are loaded onto cotton fiber to prepare catalytic functional fibers （FePc/F and CoPc/F）. The oxidative decolorization of four aze dyes with the catalytic fibers is studied. The results show that the decolorization rate of four azo dyes with FePc/F and CoPc/F can be effectively improved in the presence of H202. Reactive Red 3BSN and Acid Yellow G can be effectively decolorized by the catalytic functional fibers under neutral or weak alkali con- ditions.
