摘要
用集成了3条并行平面电极的芯片、3D打印模块代替烧杯和USB接口,构建了新型循环伏安分析装置,并用于铁氰化钾的测定,其线性回归方程为i=6.52c+1.58×103,线性相关系数R2=0.996,峰电位的平均相对标准偏差0.5%,分析性能显著优于传统循环伏安分析装置。该装置让学生接触和了解最新技术在分析测试领域的应用,为进一步开发其他实用型的便携式电化学分析装置提供条件。
A new type of the cyclic voltammetric analysis device is constructed by replacing the beaker and the USB interface with the chips of the three parallel planar electrodes and the 3D printing module,and is used for the determination of potassium ferricyanide.The equation of the linear regression is i=6.52 c+1.58×10 3,the correlation coefficient is R 2=0.996 and the average relative standard deviation of the spike potential is 0.5%.The analysis performance is significantly better than that of the traditional cyclic voltammetric analysis device.This device enables students to understand the application of the latest technology in the field of analysis and testing and provides conditions for further developing other portable electrochemical analysis devices.
