Photocatalytic Decolorization of Congo Red and Rhodamine B Using ZnO Under UV LED Irradiation
Textile wastewater containing synthetic dyes poses persistent environmental challenges due to its toxicity, chemical stability, and resistance to conventional treatment processes. This study evaluates the photocatalytic degradation performance of zinc oxide (ZnO) toward Congo Red (azo dye) and Rhodamine B (xanthene dye...
