摘要：

Dye-contaminated wastewater is hardly treated with conven-tional treatments. Consequently, there is an urgent need to develop powerful oxidation methods to ensure their removal and ensure water quality. In this framework, the scientific community is studying various treatment approaches, and this review aims to present important ideas on the applicability of electrochemical oxidation as an alternative to remove dyes from wastewater through the use of new carbon-based electrodes and dimensional stable anodes (DSAs) as commercial, envi-ronmentally friendly, and suitable electrocatalytic materials. In the discussion, the effect of the most important variables in this type of process is analyzed, namely, the type of dye, electrode material, and the different experimental conditions, that is, current density, electrolysis time, removal efficiency, color, or also abatement of the organic matter, such as total organic carbon (TOC) or chemical oxygen demand (COD).
