摘　　要：采用水热法合成了钴掺杂的铁酸锌(Co-ZFO),选取盐酸四环素作为目标污染物,用于考察复合催化剂的催化性能。通过对制备过程中的材料组分和反应条件进行优化,得到最佳制备工艺参数:Co^(2+)掺杂量质量分数为2.0%,NaOH添加量为1.28g,水热制备温度和时间分别为180℃和10h。在MW/Co-ZFO/PAA体系中,发现非自由基单线态氧(^(1)O_(2))对盐酸四环素的降解起着重要作用,并通过猝灭实验证实。同时,研究了在MW/Co-ZFO/PAA体系下不同的实际水样和分别加入无机阴离子和腐殖酸对其降解处理评价,进一步验证实际应用的可行性。结果表明,Co-ZFO催化剂具有良好的稳定性和重复性。In this paper,cobalt-doped zinc ferrite(Co-ZFO)was synthesized by hydrothermal method.Tetracycline hydrochloride(TCH)was selected as the target pollutant to investigate the catalytic performance of this composite catalyst.By optimizing the material composition and reaction conditions,the optimum preparation parameters were obtained as follows:Co^(2+)doping quantity and mass fraction was 2.0%,NaOH addition amount was 1.28 g,hydrothermal preparation temperature and time were 180℃and 10 h respectively.In the MW/Co-ZFO/PAA system,it was found that nonradical singlet oxygen(^(1)O_(2))played an important role in the degradation of TCH,which was confirmed by quenching experiments.Meanwhile,the degradation treatment evaluation of different actual water samples and the addition of inorganic anions and humic acid in the MW/Co-ZFO/PAA system were studied,further verifying the feasibility of its practical application.The results show that the Co-ZFO catalyst has good stability and repeatability.
