摘　　要：以高炉矿渣为原料,经酸、碱浸提得富钙钛矿型高炉矿渣,通过X射线荧光光谱(XRF)、X射线衍射(XRD)、扫描电子显微镜(SEM)对其组分、物相、形貌进行了表征。以甲基橙为降解物研究了投加量、溶液pH值及降解时间对富钙钛矿型高炉矿渣光催化性能的影响。实验结果表明,催化剂用量为0.5 g·L^(-1),溶液pH值为3、经紫外-可见光照5 h后,其光催化降解率可达到97.06%。The rich perovskite-type blast furnace slag was extracted from blast furnace slag by acid and alkali leaching. The composition phase and morphology of the blast furnace slag were analyzed by X-ray fluorescence spectroscopy（ XRF）,X-ray diffraction（ XRD） and scanning electron microscopy（ SEM）. The effect of catalyst dosage,pH value and time on photocatalytic properties of perovskite-rich blast furnace slag were studied using methyl orange as degradation material. The results show that when the amount of catalyst was 0. 5 g ·L^（-1） and the pH value of methyl orange solution was 3,the degradation rate could reach 97. 06 after 5 h of UV-Vis irradiation.
