Co3O4/ZIF-67活化过一硫酸盐降解磺胺二甲嘧啶的机制研究
A study on mechanism of sulfamethazine degradation by per-oxymonosulfate activation via Co3O4/ZIF-67
摘要
Abstract
In response to the increasingly severe problem of antibiotic contamination in aquatic environments,it is the aim to develop a stable catalyst that can efficiently activate peroxymonosulfate(PMS)to achieve rapid degradation of the typical antibiotic sulfamethoxazole(SMZ).A modified Co-ZIF-67(Co3O4/ZIF-67)materialwas synthesized via a fac-ile hydrothermal method and applied for efficient PMS activation to remove SMZ from water.The catalyst was charac-terized by XRD,SEM,EDS,BET,and XPS,and the successful formation of Co3O4/ZIF-67 was confirmed.Further ex-perimental results showed that 96%of SMZwas degraded within 30 minutes in the Co3O4/ZIF-67/PMS system.The elec-tron transfer between Co2+and Co3+in the catalyst played a crucial role in the efficient activation of PMS.Both free radi-cal pathways(SO4•-,·OH,and O2•-)and a non-radical pathway(¹O2)contributed synergistically to PMS activation for SMZ degradation.Intermediate products of SMZ degradation were identified using high-performance liquid chromatog-raphy-mass spectrometry(HPLC-MS),and four potential degradation pathways were proposed.After four consecutive reaction cycles,the Co3O4/ZIF-67/PMS system maintained a degradation efficiency of 63%,indicating its potential ad-vantage for environmental applications.关键词
