研究了３，５－二硝基水杨酸在ｐＨ＝３．０的盐酸介质中的阴极波特性，其二阶导数还原峰电流Ｉｐ＂（Ｅｐ＂＝—０．３６ＶｖｓＳＣＥ）与浓度在５．０×１０－８～１．０×１０－５ｍｏｌ／Ｌ范围内具有良好的线性关系，ＲＳＤ＝０．５５％（８次平行实验），检测限为１．８×１０－８ｍｏｌ／Ｌ。通过循环伏安等方法证明３，５－二硝基水杨酸在汞电极上为一含吸附的受扩散控制的不可逆过程。此外，还研究了人体内常见微量物质及表面活性剂对Ｉｐ＂的影响。
The cathode wave properties of 3,5-dinitrosalicylic acid in hydrochloric acid at pH = 3.0 were studied. The second derivative reduction peak current Ip “(Ep” = -0.36 VvsCE) There was a good linearity in the range of 0 × 10-8 ~ 1.0 × 10-5mol / L with RSD = 0.55% (eight parallel experiments) and the detection limit was 1.8 × 10-8mol / L. Cyclic voltammetry and other methods to prove 3,5 - dinitrosalicylic acid in the mercury electrode is an adsorption-controlled diffusion process irreversible process. In addition, also studied the human body common trace substances and surfactants on the impact of Ip ".
