In the present study. magnesium oxide/granular activated carbon (MgO/GAC) composite as a catalyst was synthesized using the sol-gel method and its catalytic potential was investigated in the presence of ultraviolet (UV) irradiation for the removal of cephalexin (CLX) in a batch mode reactor. Then. the characterization of the MgO/GAC composite was determined by X-ray diffraction (XRD) ... https://www.spidertattooz.com/WAC-4011-LED-Horizontal-Step-Light-Colorscaping/
