[目的]考察高铁酸钾与过氧化氢联用对水体中氟苯尼考的降解效果。[方法]以高铁酸钾与氟苯尼考的摩尔比、过氧化氢与高铁酸钾的摩尔比、反应体系的pH值以及反应时间作为考察因素,设计4因素5水平正交试验,采用高效液相色谱法测定氟苯尼考浓度,以氟苯尼考降解率作为指标,筛选最佳降解条件。[结果]通过正交试验获得的最佳降解条件:高铁酸钾与氟苯尼考的摩尔比为45∶1、过氧化氢与高铁酸钾的摩尔比为1∶1、反应体系的pH值为7、反应时间为45 min。[结论]高铁酸钾与过氧化氢联用可有效降解水体中的氟苯尼考。

[Objective]The purpose of this study was to investigate the degradation effect of potassium ferrate combined with hydrogen peroxide on florfenicol in water.[Method]A 4-factor 5-level orthogonal test was conducted using the molar ratio of potassium ferrate to florfenicol,the molar ratio of hydrogen peroxide to potassium ferrate,the pH value of the reaction system,and the reaction duration as the factors.The concentration of florfenicol was determined by high performance liquid chromatography,and the degradation rate of florfenicol was used as an evaluation index to determine the optimal degradation conditions.[Result]The optimal degradation conditions obtained from the orthogonal test were as follows:the molar ratio of potassium ferrite to florfenicol was 45∶1,the molar ratio of hydrogen peroxide to potassium ferrite was 1∶1,the pH value of the reaction system was 7,and the reaction duration was 45 min.[Conclusion]The combination use of potassium ferrite and hydrogen peroxide could effectively degrade florfenicol in water.
