Tetracycline removal from wastewater via g-C3N4 loaded RSM-CCD-optimised hybrid photocatalytic membrane reactor

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Jan. 12, 2024

In this study, a split-type photocatalytic membrane reactor (PMR), incorporating suspended graphitic carbon nitride (g-C3N4) as photocatalyst and layered polymeric composite (using polyamide, polyethersulfone polysulfone polymers) was fabricated to remove tetracycline (TC) from aqueous solutions the world's second most used discharged antibiotic in wastewater. The synthesised melamine by ultrasonic-assisted thermal polymerisation method and, along with membrane, characterised using various methods, including Brunauer-Emmett-Teller analysis (BET), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), Ultraviolet-visible (UV-Vis). PMR process optimised, Design-Expert software for removal terms of UV irradiation time, pH, loading, concentration, separation iteration. It revealed that membrane-integrated sustainable system could effectively produce clean water simultaneous solution. maximum 94.8% obtained at concentration 22.16 ppm, pH 9.78 0.56 g/L time 113.77 min after six times passing membrane. showed reasonable reusability about 25.8% drop TC efficiency seven cycles optimal conditions. outcomes demonstrate promising performance proposed suggest it can be scaled an effective approach supply antibiotic-free water.
