Abstract

This paper presents the functionalization of glassy carbon electrode with Molecularly Imprinted Polymer (MIP) nanolayers for the electrochemical analysis of anthracene (ANT), a water micropollutant that lacks a low-cost reliable commercial electrochemical sensor. Building on our previous work, we have optimized the ANT detection method, to significantly enhance its sensitivity [1]. To minimize environmental impact we carefully selected the development conditions for the MIP-Glassy Carbon Electrode (MIP-GCE). The functionalization was achieved by electropolymerization of pyrrole in the presence or absence of ANT molecules yielding MIP and Non-Imprinted Polymer (NIP) films, respectively. The electrochemical detection was achieved via square wave voltammetry, yielding remarkable performance values for the MIP-GCE sensor. Notably, the Limit of Detection (LOD), was as low as 1 ng.L⁻¹ (5.61 × 10⁻¹² M) in natural waters, representing a remarkable thousand-fold improvement compared to our preliminary study.

电化学参数对MIP玻碳电极SWV检测蒽的影响

本文介绍了分子印迹聚合物（MIP）纳米层玻璃碳电极的功能化，用于蒽（ANT）的电化学分析，这是一种缺乏低成本可靠的商用电化学传感器的水微污染物。在之前工作的基础上，我们优化了ANT检测方法，显著提高了其灵敏度[1]。为了尽量减少对环境的影响，我们仔细选择了mip -玻碳电极（MIP-GCE）的开发条件。在有或没有ANT分子的情况下，通过电聚合吡咯实现功能化，分别得到MIP和非印迹聚合物（NIP）膜。电化学检测是通过方波伏安法实现的，为MIP-GCE传感器提供了显著的性能值。值得注意的是，检测限（LOD）低至1 ng。L−1 (5.61 × 10−12 M)，与我们的初步研究相比，显着提高了1000倍。

期刊介绍： The Journal of Electroanalytical Chemistry is the foremost international journal devoted to the interdisciplinary subject of electrochemistry in all its aspects, theoretical as well as applied. Electrochemistry is a wide ranging area that is in a state of continuous evolution. Rather than compiling a long list of topics covered by the Journal, the editors would like to draw particular attention to the key issues of novelty, topicality and quality. Papers should present new and interesting electrochemical science in a way that is accessible to the reader. The presentation and discussion should be at a level that is consistent with the international status of the Journal. Reports describing the application of well-established techniques to problems that are essentially technical will not be accepted. Similarly, papers that report observations but fail to provide adequate interpretation will be rejected by the Editors. Papers dealing with technical electrochemistry should be submitted to other specialist journals unless the authors can show that their work provides substantially new insights into electrochemical processes.
