Performance of commercial polyamide membranes in pervaporation for dye removal: Impact of dye classes, colors, and surfactants

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Water reclamation in the textile industry is essential to reduce environmental impacts associated with high water consumption and pollutant discharge. Among emerging technologies, pervaporation (PV) has gained attention due to its high selectivity and efficiency in contaminant removal. However, there is still a lack of comprehensive
