Environmentally Friendly UV-C Excimer Light Source with Advanced Oxidation Process for Rapid Mineralization of Azo Dye in Wastewater.

ABSTRACT: Wastewater discharged from the textile industry contains approximately 15% unfixed dyes, predominantly 60-70% azo dyes. These unfixed dyes are a major environmental concern due to their persistence and potential toxicity. In this paper, an environmentally friendly mercury-free XeI* excilamp emitting 253 nm UV light is reported, and the same has been utilized for the degradation of azo dyes using the advanced oxidation process (AOP) with TiO₂/H₂O₂. A new process is developed in which one electrode of excilamp is coated with TiO₂ nanoparticles that improves the efficiency of the dye degradation. Additionally, the effects of varying TiO₂ loading concentrations, XeI*-excimer light intensity, starting dye concentration, suspension pH, and H
