摘要(Abstract)：

合成了以对苯二甲酸为配体的MIL-125 (Ti)和UiO-66 (Zr),并以其为前驱体,分别制备了TiO_2/C_(1000)、ZrO_2/C_(1000)纳米材料.利用X射线衍射仪、扫描电镜、气体吸附仪对材料进行物相、形貌、比表面积的研究.结果表明:ZrO_2/C_(1000)主要表现为介孔材料,而TiO_2/C_(1000)为明显的微/介孔材料.采用循环伏安法对比TiO_2/C_(1000)、ZrO_2/C_(1000)纳米材料修饰玻碳电极(GCE)检测甲基对硫磷(MP)的电化学行为,结果表明BET较小的TiO_2/C_(1000)对MP有较好的检测效果.最优条件下,MP在TiO_2/C_(1000)/GCE上的线性范围为2～40μg·m L^(-1),检测限为1. 27μg·m L(-1),检测限为1. 27μg·m L^(-1)(S/N=3).
