Water pollution caused by textile dyes is a critical environmental issue, significantly impacting aquatic ecosystems and human health. Photocatalysis has emerged as a promising solution to this problem, using light to activate catalysts that degrade organic pollutants. Titanium dioxide (TiO2), in particular, is a widely used photocatalyst for its strong oxidative properties under UV light. This study explores the degradation of Rhodamine B (RhB), a common and persistent textile dye, using carbon-doped TiO2 (C-TiO2) photocatalysts under UV-C light. The impact of various operating parameters, such as pH, initial RhB concentration, photocatalyst amount, and irradiation time, has been investigated. The results showed that at a pH of 9, a dye concentration of 10 mg/L, a photocatalyst amount of 25 mg, and an irradiation time of 90 min, the 6% C-TiO2 achieved the highest photocatalytic RhB removal of 74% under UV-C light.
