摘　　要：以α-FeOOH纳米棒为模板,通过高温烧结法制备了磁性CuFe2O4纳米棒,并研究其芬顿氧化降解刚果红染料的性能。结果表明CuFe2O4纳米棒在150min内可以有效降解90%以上的刚果红染料,经过5次循环后,降解率并无明显下降,同时还考察了其他反应条件对降解率的影响。这种新型磁性芬顿试剂在水处理方面有较好的应用前景。Magnetic CuFe2 04 nanorods catalyst was synthesized via sintering process with the ccFeOOH nano- rods template, and the Fenton oxidation activity of CuFe2O4 nanorods was evaluated by removal of Congo red （CR） dye. These results showed that CuFe2 O4 nanorods could be used as an effective Fenton oxidation catalyst capable of removing 90% CR within 150 min. The catalyst could be reused with no considerable loss in oxidation activity as proved for 5 consecutive cycles. The influence of reaction conditions on the degradation of CR was also revealed. This opens new perspectives for the preparation of magnetic catalyst based on biopolymers and the effective treatment of aqueous hazardous dyes.
