Abstract
The solvent extraction of silver (I) and palladium (II) ions with 25,2 6,27, 28-tetrakis(acetomethoxy)-5,11,17,23-tetrakis(1, 1,3,3-tetrameth ylbutyl)calix[4]arene (1) in chloroform from nitric acid solution was investigated. The compound 1 was capable of highly selectively extract ing silver over palladium from about 1 mol dm(-3) nitric acid solution and was effective in removing trace amounts of silver from a large ex cess of palladium. The coordination site of silver ion on 1 was also d etermined from the chemical shift in the H-1-NMR spectra.
