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0.05~30 mmol/L,检测限为0.00608 mmol/L；BrO3-的检测线性范围为0.05~25 mmol/L,检测限为0.0127 mmol/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 GO -HPCS-MoFe composite to IO3 - and BrO3 - was studied.The results revealed that the electrocatalytic re-duction currents augmented linearly with of IO3 - concentration in the range of 0.05 mmol/L to 30 mmol/L with a detection limit of 0.00608 mmol/L,and increased linearly with of BrO3 - concentration in the range of 0.05 mmol/L to 25 mmol/L with a detection limit of 0.0127 mmol/L,respectively.
