Abstract
New xanthic acid derivatives containing the bisbutyl polymethylene gro up were used for silver extraction in 0.1M NaClO4. Solvent extraction results showed that silver extraction was established through 1:2 (sil ver:ligand) complexes. The stabilities of the extractable complexes we re determined based the length of the polymethylene chain between the donor atoms and the presence of a neighboring functional group within the structure of the ligands, as revealed by the K-ex values. The prob able extraction mechanism (extraction and back-extraction) and interfe rences are also discussed.
