摘　　要：采用沉淀法制备钙钛矿SrTiO3粉体,通过X线衍射图谱(XRD)、扫描电镜(SEM)等分析方法对样品的晶体结构和表观形貌进行表征,并研究其对甲基橙溶液的脱色性能。结果表明,当SrTiO3添加量为0.1 g,光照时间为90 min,p H值为4.0的甲基橙溶液的脱色率可达97.4%。SrTiO3对甲基橙溶液有良好的脱色效果。SrTiO3 powders were synthesized by precipitation method and characterized by XRD and SEM. The decolorization of particles for methyl orange was also investigated. The results show that the decolorization for p H 4.0 methyl orange solutions can reach over 97.4% as the dosage of SrTiO3 is 0.1 g and the reaction time is 90 min. SrTiO3 has good decolorizing effect on methyl orange solution.
