摘　　要：利用羟丙基壳聚糖（HPCS）将石墨烯（GO）和Keplerate型钼酸盐（MoFe）复合,制备了一种新颖的具有良好催化活性的氧化石墨烯-壳聚糖-钼酸盐（GO-HPCS-MoFe）复合材料.运用循环伏安法测试了复合材料对IO3-和BrO3-的响应.结果表明,GO-HPCS-MoFe复合材料的电催化还原电流强度随IO3-和BrO3-浓度的增大而增大,IO3-的检测线性范围为0.05~30mmol/L,检测限为0.00608mmol/L;BrO3-的检测线性范围为0.05~25mmol/L,检测限为0.0127mmol/L.In this paper,a novel graphene oxide-hydroxypropyl chitosan-MoFe（GO-HPCS-MoFe）composite with good electrocatalytic activity was prepared.The electrochemical response of the GOHPCS-MoFe composite to IO3- and BrO3- was studied.The results revealed that the electrocatalytic reduction currents augmented linearly with of IO3- concentration in the range of 0.05mmol/L to 30mmol/L with a detection limit of 0.00608mmol/L,and increased linearly with of BrO3- concentration in the range of 0.05mmol/L to 25mmol/L with a detection limit of 0.0127mmol/L,respectively.
