Advanced Treatment of Direct Dye Wastewater Using Novel Composites Produced from Hoshanar and Sunny Grey Waste

The present project is designed to investigate the potential of hoshanar and sunny grey marble wastes remove direct violet 51 dye from wastewater using adsorption process. effect different parameters such as pH, adsorbent dose, initial concentration, contact time were studied optimize results Different isothermic models (Temkin, Langmuir isotherm, Freundlich Harkin Jura, Dubinin-Radushkevich models) kinetic (pseudo-first order pseudo-second order) employed data find out best fit model, i.e., isotherm model. Marble waste composites also characterized by techniques scanning electron microscopy (SEM) for surface morphology Fourier transform infrared spectroscopy (FTIR) determine chemical arrangements, structure, functional groups adsorbents. Hoshanar treated with a mixture potassium ferricyanide, sodium meta silicate showed maximum capacity 105.31 mg/g compared untreated (67.19.45 mg/g). So, conversion HM into HMPS makes it an affordable, efficient, available treatment.
