Sunlight mediated enhanced removal of metoprolol using graphitic carbon nitride (g-C3N4)

Abstract. Graphitic carbon nitride (g-C3N4) is a photocatalyst that has recently been given lot of attention due to its effectiveness in wastewater and environmental treatment, solar energy utilization, biomedical applications, etc. In this study, g-C3N4 was synthesized characterized carry out the degradation metoprolol tartrate salt (MET), which classified as an emerging contaminant. MET one most commonly used pharmaceuticals treat patients with cardiovascular diseases disorders, common disease Malaysia. Recent discoveries surface waters drinking water raise awareness concerns. using solid urea by placing it muffle furnace 550°C for 3 hours. The photocatalytic activities were investigated photodegradation MET, different dosages added into MET-containing solution, dark reaction carried 24 hours complete adsorption equilibrium. Various physical chemical analyses conducted elucidate properties g-C3N4, such FESEM, FTIR UV-Vis. absorbance reflectance graphs show there will be higher absorption visible light spectra. results optimum dosage 10 ppm 0.3 g g-C3N4. Under sunlight irradiation 4 hours, achieved 54.6% removal. Hence, proves nanosheet can applied remove complex pollutants under irradiation. This path alternative removal method sustainable approach.
