Indirect Amperometric Detection of Aliphatic Amine in Flow System

本文研究了N-羟基邻苯二甲酰亚胺（NHPI）在流动体系中对脂肪胺的安培检测。通过丁胺-NHPI体系在0.1M高氯酸四乙基铵/乙腈中的循环伏安法，讨论了该技术的原理。证明了相对于潜在依赖性和观察到的峰电流与高达120 ng进样的胺量之间的线性关系的检测的优先级。

N-Hydroxyphthalimede(NHPI) was used for amperometric detection of aliphatic amines in flow systems by monitoring the current of amine-NHPI complexes. The principles of the tecnique were discussed through cyclic voltammetries of butylamine-NHPI systemes in 0.1M tetraethyl-ammonium perchlorate/acetonitrile. The priority of the detection with respect to the potential dependence and a linear relationship between the observed peak current and the amount of the amine up to 120 ng injection were demonstrated.
