| Summary: | Herein, adsorption process based on new adsorbent was utilized to remove copper ion (Cu(II)), an environmental pollutant, from water. The reprocessing of powder chitosan into a highly porous bead would have the advantage for the industrial treatment of water. Chitosan-deep eutectic solvent (DES) beads were prepared from chitosan and DESs. The DESs used were choline chloride-urea (DES A) and choline chloride-glycerol (DES B). Both chitosan-DES beads were used to remove Cu(II) from an aqueous solution. Based on the characterisation results, chitosan-DES A showed a higher chemical and thermal stability when compared to chitosan-DES B. For type of adsorbents, chitosan-DES B showed a higher removal percentage of Cu(II) (90.92 %) than chitosan-DES A (7.5 %). Therefore, chitosan-DES B was chosen as the preferred adsorbent for Cu(II). The optimum conditions for the removal of Cu(II) from aqueous solution were using 0.09 g of chitosan-DES B with 40 min of shaking time and 1 mg L-1 of initial concentration. |
