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。Bi OI 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 Bi OI is used to degrade levofloxacin hydrochloride( LEV). Experimental results show that Bi OI 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 Bi OI.
