本文介绍 Nafion 修饰碳纤维园盘微电极的制备及其伏安特性研究;用线性扫描阳极溶出法测定人体头发中镉离子的含量;电极面积固定,重现性好,方法简便;镉的峰电流在其浓度为1×10~(-7)～9×10~(-6)及10~(-6)～9×10~(-6)范围内有良好的线性关系,适用于阳极溶出。
In this paper, the preparation of Nafion modified carbon fiber disk microelectrode and its volt-ampere characteristics were studied. The content of cadmium in human hair was determined by linear scanning anodic stripping. The electrode area was fixed and the reproducibility was good. The peak current of cadmium The concentration ranged from 1 × 10 -7 to 9 × 10 -6 and the linear range of 10 -6 to 9 × 10 -6 was suitable for anodic dissolution.
