Abstract
The electrochemical determination of chemical oxygen demand (COD) presents a promising alternative to the standard method, addressing concerns related to toxic chemicals, extended measurement time, and automation challenges. This review aims to comprehensively examine the current state of research and offer insights for future advancements. The discussion spans three key areas: working electrode materials (including Cu-based, carbon-based, Boron-Doped Diamond (BDD), and PbO2), electrochemical methods (amperometry, coulometry, and voltammetry), and measurement setups. Special emphasis is placed on exploring the dependencies of the amperometric method on organic compounds and discerning the distinct application scopes of various electrochemical methods. Future perspectives are outlined for each research aspect. The review also delves into the evaluation of developed methods, proposing measures for a more standardized and cohesive evaluation approach. Through these efforts, the review seeks to propel research towards the practical application of electrochemical COD determination.
