高铁酸钾与过氧化氢联用对水体中氟苯尼考的降解作用OACSTPCD

[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.
