Conventional separation methods are not suitable for recovering palladium present in low concentrations in ore leaching solutions. In this study, a novel isopentyl sulfide (S201)-impregnated α-MnO₂ nanorod adsorbent (BISIN) was prepared, characterized, and applied for the selective adsorption and separation of palladium from the leaching liquor of ores. Batch studies were carried out, and the m...
Air and moisture stable homoleptic bis(diimidazolylidine)nickel(II) complexes, ([(diNHC)(2)Ni](2+)) 3a,b and their corresponding silver(I) 4a,b and palladium(II) 5a,b complexes were synthesized and characterized by NMR and single crystal X-ray analysis. The catalytic potential of complex 3a was assessed in Mizoroki-Heck and Suzuki-Miyaura coupling reactions. In the Suzuki-Miyaura coupling react...
The chelating tendencies of the alpha amino acids with platinum group metal ions are well known; with the dibasic acids, complexes have been reported involving palladium(II) and platinum (II) with both aspartic and glutamic acids. There is no mention of the successful synthesis of complexes between these acids and rhodium (III), however. This communication reports a method of preparation for th...
Palladium isolation and refining through solvent extraction suffer from limited stability of commercial reagents or availability robust in nitrate media. Several performing solvents based on diamide have been proposed, but their preparation requires synthetic chemistry skills. In the present work, we propose use readily accessible N,N,N’,N’-tetrahexylmalonamide (THMA). This reagent revealed sup...
