| 논문초록 | Due to plenty functional groups, easy proccessibility and hydrophilicity, natural polymers are considered as highly promising bio-sorbent for the recovery of valuable metals in liquid source. In this study, I introduced two different case studies for recovering useful metals by using biopolymeric material as bio-sorbent. At first, alginate was applied for the strontium(Sr) recovery from seawater. Ca cross-linked alginate polymer exhibited excellent selectivity towards Sr in the presence of Na, K and Mg. By considering the Sr recovery system design, bead and foam shaped Sr adsorbent was synthesized. Secondly, cellulose nano fibril(CNF) was applied for the recovery of the Platinum(Pt) from waste catalyst leachate after modification with polyethyleneimine(PEI) which is Pt metal adsorbing ligand. Due to the highly negative charge of cellulose, PEI density on CNF could be increased up to 40% and excellent Pt adsorption capacity was obtained in the simulated catalyst leaching solution. |
