Aminoquinolines are widely used as antimalarial drugs and thus there is an ever increasing demand for their determination. In this paper, non‐traditional carbon film electrode developed in our laboratory (CFE) with easily replaceable carbon film was used for the determination of 5‐aminoquinoline (5‐AQ) and compared with well‐established commercially available carbon screen printed electrode (CSPE) and gold screen printed electrode (AuSPE). Electrochemical behavior of 5‐AQ was characterized by cyclic and differential pulse voltammetry. Differences in electrochemical behavior of 5‐AQ at different electrodes were evaluated. Determination of 5‐AQ was carried out by differential pulse, square wave, and direct current voltammetry. Practical applicability of the method was verified by direct determination of 5‐AQ in model samples of drinking and river water. Achieved limits of quantitation were in submicromolar concentrations. It was found out that novel CFE in terms of overall performance is in most aspects superior to routinely used commercially available CSPE and AuSPE.

碳膜电极和碳金丝网印刷电极上伏安法测定5-氨基喹啉的比较研究

氨基喹啉被广泛用作抗疟药，因此对其测定的需求不断增加。本文将在我们实验室（CFE）中开发的具有易于更换的碳膜的非传统碳膜电极用于测定5-氨基喹啉（5-AQ），并将其与公认的市售碳丝网印刷电极（CSPE）进行比较）和金丝网印刷电极（AuSPE）。5-AQ的电化学行为通过循环和差分脉冲伏安法进行表征。评估了5AQ在不同电极上的电化学行为差异。5-AQ的测定通过差分脉冲，方波和直流伏安法进行。通过直接测定饮用水和河水模型样品中的5-AQ，验证了该方法的实际适用性。达到的定量限为亚微摩尔浓度。已经发现，就整体性能而言，新颖的CFE在大多数方面都优于常规使用的市售CSPE和AuSPE。
