The S-TETA sorbent material was palladium(II) specific. Pd(II) loaded on the silica column was recovered using 3% m/v thiourea solution as the eluting agent. Separation of platinum and palladium was achieved by selective stripping of [PtCl6]2− with 0.5 M of NaClO4 in 1.0 M HCl while Pd(II) was eluted with 0.5 M thiourea in 1.0 M HCl. The separation of palladium (Pd) from a mixture containing platinum (Pt), iridium (Ir), and rhodium (Rh) was successful on silica functionalized with triethylenetriamine (TETA) showing specificity for palladium(II) and a loading capacity of 0.27 mg/g. S-TETA showed potential for use in the recovery of palladium from platinum group metals such as from solutions of worn out automobile emission control catalytic convertors and other secondary sources.]]> Wed 08 May 2024 16:00:16 SAST ]]> Synthesis, photophysics and photochemistry of phthalocyanine-ɛ-polylysine conjugates in the presence of metal nanoparticles against Staphylococcus aureus https://commons.ru.ac.za/vital/access/manager/Repository/vital:51257 Wed 07 Aug 2024 16:02:17 SAST ]]> Characterization of some amino acid derivatives of benzoyl isothiocyanate: Crystal structures and theoretical prediction of their reactivity https://commons.ru.ac.za/vital/access/manager/Repository/vital:74686 Wed 07 Aug 2024 15:55:23 SAST ]]> Benzimidazole or Diamide From a Reaction of Diamines and Carboxylic Acids or Acid Chlorides: Crystal Structures and Theoretical Studies https://commons.ru.ac.za/vital/access/manager/Repository/vital:74685 Wed 07 Aug 2024 15:55:22 SAST ]]> The development of palladium (II)-specific amine-functionalized silica-based microparticles https://commons.ru.ac.za/vital/access/manager/Repository/vital:50903 0.99.
