Abstract

A novel electrochemical sensor for determining trace levels of Hg, Pb, and Zn ions in water using square wave voltammetry (SWV) is reported. The sensor is based on a platinum electrode (Pt) modified by poly(3,4-ethylenedioxythiophene) and , -bis-(carboxymethyl)-l-lysine hydrate (NTA lysine) PEDOT/NTA. The modified electrode surface (PEDOT/NTA) was prepared via the introduction of the lysine-NTA group to a PEDOT/N-hydroxyphthalimide NHP electrode. The (PEDOT/NTA) was characterized via cyclic voltammetry (CV), Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM). The effects of scan rates on the electrochemical properties of the polymer electrode were also investigated. The electrochemical results were used to estimate the coverage of the electrode polymer surface and its electrostability in background electrolyte solutions. Several analytical parameters, such as polymer film thickness, metal deposition time, and pH of the electrolyte, were examined. Linear responses to Hg, Pb, and Zn ions in the concentration range of 5-100 μg L were obtained. The limits of detection (LODs) for the determination of Hg, Pb, and Zn ions were 1.73, 2.33, and 1.99 μg L, respectively. These promising results revealed that modified PEDOT/NTA films might well represent an important addition to existing electrochemical sensor technologies.

摘要

报道了一种用于使用方波伏安法（SWV）测定水中痕量汞、铅和锌离子的新型电化学传感器。该传感器基于由聚（3,4 - 乙撑二氧噻吩）和N - （羧甲基）-L - 赖氨酸水合物（NTA赖氨酸）修饰的铂电极（Pt），即PEDOT/NTA。通过将赖氨酸 - NTA基团引入PEDOT/N - 羟基邻苯二甲酰亚胺（NHP）电极制备修饰电极表面（PEDOT/NTA）。通过循环伏安法（CV）、傅里叶变换红外（FTIR）光谱和扫描电子显微镜（SEM）对（PEDOT/NTA）进行表征。还研究了扫描速率对聚合物电极电化学性质的影响。利用电化学结果估计电极聚合物表面的覆盖率及其在背景电解质溶液中的电稳定性。考察了几个分析参数，如聚合物膜厚度、金属沉积时间和电解质的pH值。在5 - 100 μg/L浓度范围内获得了对汞、铅和锌离子的线性响应。测定汞、铅和锌离子的检测限（LOD）分别为1.73、2.33和1.99 μg/L。这些有前景的结果表明，修饰的PEDOT/NTA膜很可能是现有电化学传感器技术的重要补充。
