An historical overview covering the field of electroanalytical metal cations speciation in freshwaters is presented here, detailing both the notable experimental and theoretical developments. Then, a critical review of the progress in the last five years is given, underlining in particular the improvements in electrochemical setups and methodologies dedicated to field surveys. Given these recent achievements, a road map to carry out on-site dynamic metal speciation measurements is then proposed, and the key future developments are discussed. This review shows that electroanalytical stripping techniques provide a unique framework for quantitatively assessing metals at trace levels while offering access to both thermodynamic and dynamic features of metal complexation with natural colloidal and particulate ligands.
本文提供了一个涵盖新鲜水中电分析金属阳离子形态领域的历史概述，详细介绍了显著的实验和理论进展。然后，对过去五年的进展进行了批判性回顾，特别强调了电化学装置和专门用于现场调查的方法学的改进。鉴于这些最新进展，提出了一个进行现场动态金属形态测量的路线图，并讨论了未来的关键发展。该综述表明，电分析剥离技术为定量评估痕量水平的金属提供了一个独特的框架，同时提供了对天然胶体和颗粒配体与金属络合的热力学和动力学特征的访问。
