摘要(Abstract)：

研究了以氯化铁、硝酸镍为原料，曲拉通为修饰剂，采用水浴磁力搅拌法改性NiFe_2O_4制备M-NiFe_2O_4,并借助红外光谱、XRD、热重分析等手段对NiFe_2O_4和M-NiFe_2O_4进行结构表征，以及考察制备条件(表面活性剂种类、n(曲拉通)/n(硝酸镍)、温度),溶液pH及初始甲基橙质量浓度对M-NiFe_2O_4光降解甲基橙催化性能的影响，探讨M-NiFe_2O_4的循环稳定性和降解机制。结果表明：在n(曲拉通)/n(硝酸镍)=1/2、温度80℃条件下所制备的M-NiFe_2O_4对甲基橙有较好的降解催化性能，对于pH=3、质量浓度25 mg/L的甲基橙溶液，甲基橙降解率可达95.0%;3次循环后降解率为70.30%,循环性能良好。
