Graphitic Carbon Nitride Nanosheet as an Excellent Compound for Adsorption of Phenol

Removal of phenol and its derivatives are studied using ultrathin graphitic carbon nitride nanosheets.They were characterized by powder X-ray diffraction (XRD), Fourier Translation infrared spectroscopy(FT-IR), field emission scanning electron microscopy (FESEM), transmission electron microscopy. Phenol is a type of organic compound. While toxic to consume on its own, it‟s in many household products like mouthwash and spray cleaners. In its pure form, it may be colorless or white. It is a white crystalline solid that is volatile. It has a mildly sugary scent that might remind you of somewhere that‟s sterile, such as a hospital room. In limited quantities, it‟s available for several medical and health-related uses. The present work analyzed adsorption kinetic of phenols from aqueous solution by using graphitic carbon nitride nanosheet in batch culture methods. The effect of pH, phenol concentration, temperature, equilibrium time and adsorbent mass was tested. The process of phenol adsorption followed pseudo second-order rate expression and obeyed the Langmuir‟s model. Desorption studies with water indicate that the adsorbent could successfully retain phenol, even after five cycles. Results of experimental analysed showed that the adsorption of phenol on the surface of graphitic carbon nitride nanosheet has high yield, easy treatment, eco-friendly and nonexpensive.
