註釋

Extensive characterization (IR, UV, 1H-NMR and GC-MS) of new, non commercially available 7-substituted-8-hydroxyquinoline derivatives, 8-HQ, labelled TN 1911, TN 2181, TN 2221 and TN 2336, manufactured by Schering Berlin AG., (Germany) is reported. Hydrochloric acid and the accompanied water extraction performance of Kelex 100, TN 1911 and Lix 26 as well as the occurrence of protonated extractant in the organic phase is also discussed. Equilibrium measurements of palladium and platinum extraction by chloroform solutions of 7-substituted-8-hydroxyquinoline derivatives from aqueous chloride media demonstrated that Pd(ll) is extracted as the chelate PdQ2 whereas Pt(IV) is extracted as the ion-pair PtCl6 2- * (H2Q+) 2. The formation of the chelate PdQ2 was also confirmed with direct spectroscopic analysis. [...].
