The authors regret that there were typographical errors in the mathematical expressions listed in Section 2.6 – Separation Performance Analysis of Ti3C2Txmembrane. The formulas for Rejection Rate (Equation 2), Flux Recovery Ratio (Equation 3), and Total Flux Decline Ratio (Equation 4) were incorrectly presented. The corrected versions are provided below: • Rejection Rate (R%) [Formula presented] where Up represents the concentration of the permeated-out dye solution (after filtration), and Uf represents the concentration of the initial feed dye solution (before filtration). • Flux Recovery Ratio (FRR) [Formula presented]• Total Flux Decline Ratio (DRt) [Formula presented] Where Jw1 is the average initial water permeability, Jp is the average permeability during pollutant filtration, and Jw2 is the average recovered water permeability. We wish to emphasize that these were typographical errors in the written equations only. All calculations, data interpretations, and conclusions presented in the manuscript were based on the correct formulations. The authors would like to apologise for any inconvenience caused. © 2025 Taiwan Institute of Chemical Engineers
Ti3C2Tx MXene based membranes: A novel approach for wastewater treatment

Background: Fresh water around the world are facing rising levels of contamination from organic pollutants, largely driven by the release of various dyes from textile industries and the waste generated by the increasing use of pharmaceuticals. These pollutants pose a serious threat to the underground water and aquatic ecosystems. Methods: Membrane-based technologies are emerging as promising solutions for efficient pollutant separation and purification to address the global issue of water pollution. In this study, we investigate the use of Ti3C2Tx membranes synthesized using HF etching technique and fabricated using a simple vacuum-assisted filtration technique. Three membranes having thicknesses ∼65 µm, 97 µm, and 155 µm were developed for the water filtration experiment. Significant Findings: These membranes demonstrated high rejection rates (>95 %) and fluxes (>1000 Lm-2h-1) for 10 ppm solutions of Rhodamine B, Methyl Violet, and Levofloxacin maintaining its performance even at higher concentrations (upto 50 ppm). The membranes showed excellent stability over 10 cycles, along with strong anti-fouling properties. Additionally, they retained their performance under varying pH concentrations for each pollutant. This study highlights the potential of Ti3C2Tx-based membranes for diverse wastewater treatment applications, including industrial wastewater treatment, pharmaceutical industries, and life sciences sectors. © 2025 Taiwan Institute of Chemical Engineers
