摘要
采用超声浸渍法成功制备了锰锌铁氧体/硫化镉(MZFO/CdS)磁性异质结,并在可见光照射下以磺胺甲唑(SMZ)为目标降解物研究了MZFO/CdS的光催化性能。采用X射线衍射仪、扫描电子显微镜和透射电子显微镜分别表征了MZFO/CdS的结构和形貌。结果表明:复合MZFO有助于CdS的结晶和分散,MZFO/CdS具有很好的磁性。在pH=7、SMZ浓度为20mg/L的条件下,MZFO/CdS对SMZ的去除效果最好,相对降解率最高达到93.6%,绝对去除量最高达到35.53mg/g。
Manganese-zinc ferrite/cadmium sulfide(MZFO/CdS)magnetic heterojunction was successfully prepared by ultrasonic immersion method,and the photocatalytic properties of MZFO/CdS was studied by using sulfamethoxazole(SMZ)as the target under visible light.The structure and morphology of MZFO/CdS were respectively characterized by X-ray diffraction,scanning electron microscope and transmission electron microscope.The results showed that MZFO was beneficial to the crystallization and dispersion of CdS,and MZFO/CdS possesed good magnetic properties.When pH=7,the concentration of SMZ was 20 mg/L,MZFO/CdS had the best removal effect on SMZ,the highest relative degradation rate reached to 93.6%,and the highest absolute removal rate achieved 35.53 mg/g.
