Síntesis y caracterización de materiales poliméricos para la separación no cromatográfica de metales nobles. Separación y determinación de iridio mediante cromatografía líquida y electroforesis capilar

For the selective separation of Noble Metals, different new chelating polymers with the same functional group, based on tri-isobutylphosphine sulphide, have been synthesised. Different spacers between the polymeric matrix and the functional group were introduced during the synthetic process, varying the length and number of heteroatoms (O, S) in the spacer molecule. These polymers show a good affinity towards gold and silver ions and a lower adsorption capacity towards palladium, and do not adsorb all other noble and base metals tested ​
