摘要
研究采用水热法成功制备了磁性铁酸镍(NiFe_(2)O_(4)),并利用X射线衍射(XRD)等对磁性NiFe_(2)O_(4)的性质进行表征。在微波作用(MW)和过硫酸盐(PS)存在下,系统地开展了MW与磁性NiFe_(2)O_(4)活化过硫酸盐对水溶液中盐酸四环素(TCH)氧化反应过程的影响因素及反应机制研究。结果表明:MW和磁性NiFe_(2)O_(4)协同活化过硫酸盐体系对TCH的去除率较好,在最佳条件反应下,去除率可达到88.8%。此外,通过对pH、过硫酸盐浓度、催化剂剂量等影响因素对TCH降解效果的研究显示,磁性NiFe_(2)O_(4)可有效活化过硫酸盐,在抗生素废水处理中具有潜在的应用前景。
In this study,magnetic nickel ferrite(NiFe_(2)O_(4))was successfully prepared by hydrothermal method,and the properties of magnetic NiFe_(2)O_(4) were characterized by X-ray diffraction(XRD)and others.In the presence of microwave(MW)and persulfate(PS),the influencing factors and reaction mechanism of MW and magnetic NiFe_(2)O_(4)-activated persulfate on the oxidation process of tetracycline hydrochloride(TCH)in aqueous solution were systematically studied.The results showed that the removal rate of TCH by MW and magnetic NiFe_(2)O_(4) synergistic activated persulfate system was good,and the removal rate could reach 88.8% under the best condition.In addition,the study of the effect of pH,persulfate concentration,catalyst dose and other influencing factors on TCH degradation shows that magnetic NiFe_(2)O_(4) can effectively activate persulfate,which has potential application prospects in antibiotic wastewater treatment.
