摘要

文章通过滴涂法和电化学还原氧化石墨烯/磷钼酸溶液制备了电化学还原氧化石墨烯/磷钼酸纳米复合物。扫描电子显微镜表征所得复合物。通过安培响应曲线检测该复合物对溴酸根的电催化性能。实验结果表明电化学还原氧化石墨烯/磷钼酸/玻碳电极传感器用于检测溴酸根浓度的线性范围为0.4μM~8.99 m M,检测限为0.15μM。
        A electrochemically reduced graphene oxide-phosphomolybdic acid(ERGO-PMo A)nonacomposite was prepared by drop casting and electrochemical reduction of GO-PMo A suspension, respectively.It was characterized by scanning electron microscopy(SEM).The electrocatalytic activity of the ERGO-PMo A was indicated by Amperometric response curves. The curves show the ERGO-PMo A/GCE can be used to determine bromate concentration in a wide linear range of 0.4 μM and 8.99 m M with a detection limit of 0.15 μM.
