Abstract
In this research, the sanitary ware waste is modified by the addition of sodium hydroxide via the hydrothermal method. The obtained product was characterized utilizing different techniques such as X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and Diffuse reflectance spectroscopy (DRS). XRD showed the synthesized samples before and after calcination containing the two phases Faujasite-NaY and Sodalite. The average crystallite sizes of S17R and S17C samples were recorded from the x-ray diffraction peaks to be 24.6 and 15.4 nm, respectively. Also, the optical properties were studied using diffuse reflectance spectroscopy. The band gap and color analysis of the synthesized products were studied. The values of light and solar reflectance were determined using JISA5759 2008, and JISK5602 2008 methods. In addition, the prepared products have an efficient adsorption performance to anionic dyes (sunset yellow, naphthol green B, and amaranth dyes). The maximum adsorption capacities of S17R and S17C samples toward sunset yellow, naphthol green B, and amaranth dyes are 65.38/39.1/51.66 mg/g and 82.7/46.97/58.33 mg/g, respectively.
