摘要

采用溶剂热法制备出添加不同质量聚乙烯吡咯烷酮（PVP）改性的碘氧化铋（BiOI）粉末，通过扫描电镜、X-射线粉末衍射、紫外-可见漫反射光谱、氮气吸附和解吸附曲线对其进行表征，并将改性BiOI粉末用于光催化降解盐酸左氧氟沙星（LEV）。结果表明，改性BiOI中BiOI0.3光催化剂对盐酸左氧氟沙星的降解效果最好，接近90%，远高于未改性BiOI的降解率。

Abstract

BiOI doped by different amounts of polyvinylpyrrolidone (PVP) are synthesized via solvothermal method, and characterized by SEM, XRD, UV-Vis DRS and BET. In order to study the photocatalytic activity, the PVP modified BiOI is used to degrade levofloxacin hydrochloride (LEV). Experimental results show that BiOI 0.3 has the best degradation effect, over which the degradation rate of antibiotics approaches to 90%, much better than the 68% degradation rate over unmodified BiOI.
