摘要：
Extensive characterization (IR, UV, H-1-NMR and GC-MS) of new, non commercially available 7-substituted-8-hydroxyquinoline derivatives labeled TN 1911, TN 2181, TN 2221 and TN 2336, manufactured by Schering Berlin AG., (Germay) is reported here. GC-MS allowed for the identification of isomers present in TN 1911 and Lix 26 (Henkel) extractants. Purity, molecular weight and molarity of the active substance in the ''as received'' extractants, are also reported. Finally, 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.
