Enhanced platinum and palladium recovery from aqueous solutions: a comparative study of acylthiourea and amine-modified silica gel adsorbents
Malehlogonolo R. R. Mphahlele, Alseno K. Mosai, Hlanganani Tutu, Izak A. KotzéThe study developed TESP-BT-SG and enhanced APTES-SG synthesis, increasing ligand concentration. Both adsorbents achieved >97% Pt and Pd extraction efficiency and maintained high selectivity in the presence of other ions.
