Development of adsorbent from Teflon waste by radiation induced grafting: Equilibrium and kinetic adsorption of dyes

► Teflon scrap inherently inert and difficult to reprocess. ► Scrap converted to a hydrophilic adsorbent by radiation induced grafting of acrylic acid. ► Parameters standardized to obtain adsorbent of desired grafting extent. ► Various models used to understand adsorption mechanism, extent and kinetics of dyes BR29 and BY11.
