碘掺杂MnO2催化剂的制备及其活化过一硫酸盐降解四环素的研究
Preparation of Iodine Doped MnO2 Catalyst and Its Application for Tetracycline Degradation via Peroxymonosulfate Activation
摘要
Abstract
In this study,ammonium iodide was used as the iodine source,mixed with manganese sulfate monohydrate and ammonium persulfate in a specific ratio,and uniformly ground.By varying the calcination temperature,different iodine-doped manganese oxide catalysts(I-MnO2-1,I-MnO2-2,and I-Mn2O3)were prepared and applied to activate peroxymonosulfate(PMS)for tetracycline degradation.The results showed that the I-MnO2-1 catalyst exhibited the best performance in activating PMS for tetracycline degradation(86.9%).Within a certain range,the degradation efficiency of tetracycline increased with the dosage of the I-MnO2-1 catalyst or the concentration of PMS,with the optimal conditions being 100 mg/L of catalyst and 1 mM of PMS.This study provides a novel strategy for the rational design of highly efficient Fenton-like catalysts for wastewater treatment.关键词
