Key Points

  • This research aims to evaluate the efficiency of deep eutectic solvent-functionalized activated carbon from coconut waste for dye adsorption.
  • Functionalized activated carbon derived from coconut waste was tested for dye adsorption.
  • Adsorption efficiency was measured over five reuse cycles for various textile dyes and real wastewater samples.
  • Sustainability was assessed using EcoScale scoring.
  • The deep eutectic solvent-functionalized activated carbon showed minimal efficiency loss after five cycles of use.
  • An EcoScale score of 78 out of 100 indicates a sustainable dye removal method.
  • The adsorbent demonstrated strong performance in treating dye-contaminated wastewater samples.

Abstract

.K) at the solid-liquid interface. Additionally, T:P-DES@AC-DCW demonstrated excellent reusability over five consecutive cycles with minimal loss in efficiency and showed promising performance for the adsorption of various textile dyes and real wastewater samples. An EcoScale score of 78 out of 100 further confirms the sustainability of the proposed method for dye removal. These findings highlight the potential of T:P-DES@AC-DCW as a low-cost, eco-friendly, and highly efficient adsorbent for the treatment of dye-contaminated industrial wastewater.
