Abstract. The extensive use of synthetic dyes in various industrial applications has led to significant environmental challenges, posing threats to both human health and aquatic ecosystems. Addressing the detection and remediation of these harmful dyes is essential for minimizing their detrimental environmental effects and advancing sustainable water management practices. This study focuses on developing and evaluating electrochemical sensors designed for sensitive detection and effective degradation of toxic dyes in industrial wastewater. The aim is to improve detection sensitivity, analyze dye degradation kinetics, and contribute to eco-friendly water purification technologies that align with sustainable environmental practices. Using modified glassy carbon electrodes (GCE) with functionalized carbon nanotubes and advanced photocatalytic materials, we aim to design a platform that can detect minute concentrations of toxic dyes in aqueous systems. The electrochemical characteristics were evaluated using cyclic voltammetry, square wave anodic stripping voltammetry (SWASV), and impedance spectroscopy. Photodegradation studies were also conducted to evaluate the degradation efficiency of these sensors under natural sunlight under ambient conditions. The electrochemical sensors demonstrated exceptional sensitivity, achieving detection limits in the picomolar and nanomolar ranges for the target dyes. Photodegradation studies revealed pseudo-first order kinetics, with over 90% dye removal under natural sunlight. The developed electrochemical sensors present an innovative approach to the detection and degradation of toxic dyes in wastewater, contributing to the achievement of Sustainable Development Goals, particularly in water purification and environmental sustainability. These findings demonstrate the potential of nanomaterial-based electrochemical systems to address pressing environmental challenges.
