Ni掺杂Fe基MOF衍生物修饰阴极电芬顿体系降解水中四环素
Degradation of Tetracycline in E-Fenton System with Ni-Doped Fe-Based MOF Derivatives Modified Cathodes
摘要
Abstract
For the drawback of the narrow pH range and the generation of iron sludge of the conventional Fenton process,the Ni/Fe@PC porous carbon material is prepared in this study,which is produced by solvothermal method and high-temperature carbonization two-step process.The Ni/Fe@PC modified cathode was prepared with Ni/Fe@PC loading and then unsed for the degradation of tetracycline(TC)in the constructed elcetro-Fenton process.The electrochemical properties of the materials were characterized by electrochemical impedance(EIS)and cyclic voltammetry(CV).The effects of different influencing factors on the degradation of tetracycline in the system were investigated,and the degradation performance and mechanism of tetracycline by the system electro-Fenton were discussed.Compared with blank carbon felt electrode and Fe@PC modified electrode,Ni/Fe@PC modified electrode has better tetracycline degradation performance in heterogeneous electro-Fenton system.At room temperature,pH is 5.The initial concentration of tetracycline is 10 mg/L.The distance between the electrodes is 2 cm,and the current is 40 mA.The removal rate of tetracycline by Fe/Ni@PC modified electrode reached 90%after 90 min reaction.The Ni/Fe@PC modified electrode showed great reusability and stability.The results of free radical shielding experiments showed the main roles of HO2·/·O2-and 1O2 in the degradation of TC with Fe/Ni@PC modified electrode.关键词
