Applications of MXene for Hospital Wastewater Treatment

Abstract

Hospital wastewaters (HWW) stand out from other wastewater sources due to their high pharmaceutical content, particularly antibiotics. Tetracycline (TC) is among the most widely used antibiotics. Eliminating TC from HWW is crucial for global health, safety, and societal progress. Traditional wastewater (WW) treatment methods are ineffective against antibiotics, contributing to antibiotic resistance in WW. Thus, adsorption treatment appears as a promising approach to reduce antibiotic levels in WW. Furthermore, employing innovative nanomaterials, such as MXenes, can enhance adsorption capacity. In this study, we propose an adsorption technique utilizing MXene for antibiotic removal. We achieved an optimal removal efficiency of approximately 76% by adjusting TC concentration, MXene dosage, and pH. Experimental data for TC adsorption on MXene fitted well with the Freundlich isotherm model and pseudo-second-order kinetic model. Regenerated MXene maintained removal rates of 80%, 80%, 64%, and 28% across different cycles.
