Decolorization of Disperse Dyes in Textile Polyester Recycling Using Activated Carbon

open access: yesChemie Ingenieur Technik, EarlyView.
Decolorization of disperse dyes from disodium terephthalate solutions is examined using two activated carbons with varying pore structures and surface properties. The potential impact of pore size distribution and surface charge on the adsorption process is assessed to support optimized adsorbent selection.
