本文介绍一台流动注射阳极溶出伏安仪。仪器采用壁喷流通电极,进口喷嘴直径为0.32mm。整个系统用一台8位微机控制。实验结果表明,对5×10~(-8)M Cd(Ⅱ)连续测定34次,相对标准偏差为1.26%.溶出峰电流与浓度的线性相关系数为0.999.
This article describes a mobile injection anodic stripping voltammetry. Instrument wall jet through the electrode, the inlet nozzle diameter of 0.32mm. The entire system with a 8-bit microcomputer control. The experimental results showed that the relative standard deviation (RSD) was 1.26% when the determination of 5 × 10 -8 M Cd (Ⅱ) was continuous for 34 times, and the linear correlation coefficient of dissolution peak current and concentration was 0.999.
