Photocatalytic removal of ceftriaxone from aqueous solutions using g-C3N4

Abstract

Ceftriaxone is a one of Pharmaceutical compounds that cause pollution of water. In this research, g-C3N4 photocatalyst was synthesized and its efficiency in removal of ceftriaxone was studied. The synthesized g-C3N4 was analyzed using XRD, FTIR, FESEM,EDS and dot mapping. The effect of initial concentration of ceftriaxone, dosage of photocatalyst, irradiation time and pH was studied and based on these results, the highest removal efficiency of ceftriaxone from water was obtained about 83.4% at the concentration of 20 mg/L, pH=2 , 0.25 g/500 mL of g-C3N4 photocatalyst at 50 min of irradiation time. This study confirmed that g-C3N4 photocatalyst can be efficiently removed of ceftriaxone from water.
