| Abstract |
This research focuses on preparation of Ag-doped ZnS photocatalyst via hydrothermal technique using zinc nitrate hexahydrate [Zn(NO3)2.6H2O] as Zn2+ source, thioacetamind [CH3CSNH2] as S2- source, and deionized water as solvent. The ZnS nanostructures were characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffractometry (XRD), transmission electron microscopy (TEM), thermal gravimetric analysis (TGA), UV-vis diffuse reflection spectroscopy (UV-vis DRS), and photoluminescence spectroscopy (PL). The photocatalytic activity of ZnS samples were studied by monitoring the photodegradation of pollutants namely reactive red (RR141) azo dye, Congo red (CR) azo dye and Norfloxacin (NR) antibiotic under ultraviolet (UV) light irradiation for 240 min. Blank test was also separately carried out by irradiating the aqueous solution of the dye in absence of the photocatalyst. The initial concentration of the pollutant was fixed at 10 ppm. About 50 mg of ZnS photocatalyst was dispersed in 200 mL of pollutant solution. The samples were collected at a regular time interval during the irradiation and then was analyzed after centrifugation. The concentration of each pollutant was determined by monitoring the absorbance at its maximum wavelength (max) of 544 nm, 500 nm, and 275 nm for RR141, Congo red (CR) azo dye and NR antibiotic, respectively, using UV-vis spectroscopic analysis technique. The 10 wt% Ag doped ZnS showed the enhanced efficiency of 99.5%, 94.0%, and 44.5% toward photodegradation of RR141 azo dye, Congo red (CR) azo dye and NR antibiotic, respectively. |
