| Abstract |
Platinum, being a critical raw material, needs to be recovered from secondary sources. Herein, Pt2+-selective adsorbents were synthesized from polymerizable dithiadiamide ligands via condensation reaction between mercaptoacetamide and 脧聣-dibromoalkanes with different alkane lengths. Molecular ion imprinted polymers (MIIP) were prepared by complexing and eluting Pt2+-template in dithiadiamide ligand芒聙聰ethylene glycol dimethacrylate copolymers. MIIPs were systematically evaluated on its selective Pt2+ recovery through adsorption isotherm, kinetics, and recyclability. Selectivity tests were conducted using a simulated solution containing the predominant cations present in acid-leached spent 3-way, gasoline ACC sample and a Pt2+/Pd2+ binary solution. Data were corroborated with Density Functional Theory calculation. |
