Solvent Extraction and Separation of Silver(I) in Real Sample Using Hexaacetato Calix[6]arene

Abstract

Abstract: In this study, silver(I) was extracted at pH 11.5 into organic phase using 0.0001 M hexa-p-t-butyl-hexaacetato calix[6]arene solution in xylene after a five min equilibration period. Silver(I) was back extracted with 1 M HNO3 and determined photometrically. Log-log plot gives 1:1 stoichiometry of extracted species indicating that one ligand reacts with one mole of silver(I). The values of ∆G, ∆H and ∆S were determined by studying the extraction equilibrium at different temperatures. Quantitative separation of binary and synthetic mixtures of silver from associate elements was effectively carried out. The extraction and separation of silver(I) from real and multicomponent samples were also studied. The RSD was ≤0.5%. Keywords: Solvent extraction, Acetyl derivative, Calix[6]arene, Separation, Silver(I).
