The accumulation of dyes in waste water is increasing every day, to increase the aesthetic value of products. The dyes though used in permissible limit are further leading to adverse effects. The Sudan – III which is a diazo dye, Safranin – O is a phenazine dye, used in textile and food industries is becoming a major concern as Sudan – III is characterised as grade – 3 carcinogenic agent and Safranin – O causes cancer. The partial degradation of Sudan – III produces secondary pollutants like Napthylamine and aniline which cause adverse effect on humans and aquatic animals. The Photocatalytic degradation of Sudan – III and Safranin – O is very effective in presence of graphene based RGO@Ag nanocomposites. The morphology and structure were studied using spectroscopic and microscopic techniques such as UV-Visible spectroscopy, and powder XRD. The spectroscopy and microscopic results revealed the successfully formation of RGO@Ag nanocomposites. The photocatalytic degradation is carried in presence of Hg lamp and the degradation of dyes is confirmed by UV-Visible spectroscopy at 506 nm is 99.0% in acidic medium and 94.4% in neutral medium with catalyst having 6 cycles for Sudan – III and.
