SUMMARY:

This work focuses on the issue of high organic and saline loads in wastewater from the textile industry, which generates millions of metric tons worldwide annually. The work begins with an introduction to the problem and the presentation of the objectives set for the development of the study. In Chapter 2, a literature review is presented, addressing the impact of water pollution, various water treatment technologies, chloride-mediated electrocatalysis, and azo dyes. The following two chapters are dedicated to the experimental part, starting with Chapter 3, where a fundamental analysis of chloride behavior was conducted in an electrochemical system with an undivided cell using a Dimensional Stable Anode (Ti/SnO2-IrO2-Sb2O3) as the working electrode, varying chloride concentration in acidic, neutral, and alkaline media. The results obtained in this phase laid the foundation for Chapter 4, in which the degradation of an azo dye (methyl red) was carried out in the same electrochemical system using chlorides as mediators. This process proved to be efficient in terms of electrooxidation, reducing the energy demand associated with the degradation of the contaminant. Additionally, the formation of short-chain carboxylic intermediates was analyzed, which have significant commercial value, contributing to the Sustainable Development Goals and promoting the circular economy. In Chapter 5, an exhaustive review of the most promising photocatalytic materials was conducted, highlighting how this emerging technology could drive the development of more efficient environmental sensors. Finally, the contribution of these works to advancing the use of advanced electrochemical technologies for pollutant treatment and environmental monitoring improvement was concluded.
