Abstract:
Water pollution is the main environmental problem nowadays. Heavy discharge of industrial waste such as organic dyes is one of main reason of water pollution. For this purpose photocatalyst N/S codoped Graphene Hydrogel (N/SGH) was synthesized by hydrothermal method and was used for photocatalytic degradation of dye under irradiation of UV lamp. The N/S codoped Graphene Hydrogel was characterized by UV-Visible double beam spectrophotometer, X-Ray Diffraction pattern (XRD), Fourier transform infrared spectroscopy (FT-IR),Energy dispersive X-Ray Analysis(EDX) and Scanning electron microscope(SEM). Batch experiments of adsorption were carried out by varying solution pH, adsorbent dose, initial dye concentration and contact time. The results revealed that optimum time in which degradation is maximum is 40 minutes, the degradation of dye decrease with increase in dye concentration 10ppm methyl violet show maximum degradation of about 93.3%, The pH of solution was varied from 2 to 14 for methyl violet dye and also dye adsorption capacity increased with increased adsorbent dosage up to 0.04 g, where degradation is 98.2%.
