摘要
目的:采用多金属氧酸盐基主客体框架材料修饰玻碳电极测定香草酸的浓度。方法:按照多酸基主客体框架材料合成方法,选择钒取代的磷钼酸(PMoV)与MIL-100(Fe)复合,合成了一种稳定的基于多酸的主客体金属有机框架材料PMoV@MIL-100(Fe)。通过溶液法将金属纳米粒子与PMoV@MIL-100(Fe)复合,制备功能性复合材料PMoV@MIL-100(Fe)@Pt,并用来修饰玻碳电极,检测香草酸,制备香草酸电化学传感器。结果:在最佳条件下,该香草酸电化学传感器表现出宽的线性范围和较高灵敏度。可以在温和的条件下对香草酸进行快速灵敏的检测,且具有出色的稳定性。结论:本实验构建的电化学传感器为检测香草酸提供了新思路。
Objective:To determine the concentration of vanillic acid by polyoxometal-based host-guest frame material modified glass carbon electrode.Methods:A stable polyacid-based host-guest metal-organic framework material PMoV@MIL-100(Fe)was synthesized by combining vanadium-substituted phosphomolybdic acid(PMoV)with MIL-100(Fe)according to the synthesis method of polyacid-based host-guest framework materials.Functional composite material PMoV@MIL-100(Fe)@Pt was prepared by composite metal nanoparticles with PMoV@MIL-100(Fe)by solution method,and was used to modify glassy carbon electrode,detect vanillic acid,and prepare vanillic acid electrochemical sensor.Results:Under optimal conditions,the vanillic acid electrochemical sensor showed wide linear range and high sensitivity.Rapid and sensitive detection of vanillic acid could be performed under mild conditions with excellent stability.Conclusion:The electrochemical sensor constructed in this experiment provides a new idea for the detection of vanillic acid.
