The extraction of copper(I1) ions in the presence of salicylate ions, using a solution of the salicylate form of Aliquat 336 in chloroform, involves two simultaneous processes depending on the pH and on the salicylate concentration of the aqueous phase. The composition of the species formed in the c

✦ Synopsis
On the basis of the differences between the stability constants of complexes of D-and L-aminodiols with copper ions, an ion-exchange chromatographic method using copper(I1) ions as complex-forming agents was developed for the quantitative separation of pairs of optical isomers. The stability constants of some complexes were determined. The distribution coefficients of two enantiomers were examined by static batch and elution methods. The optimal conditions of the separation and the composition of the eluent are discussed.
