“…As can be seen from these figures, the Rm value of sample ion is not independent of the type of the coion in the eluant. All the plots give the straight lines with the negative slopes, and the value of the slope of the each plot is in agreement with the calculated one by eq 35 within the experimental error (22). This result indicates that the exclusion effect is not the predominant factor controlling the separation mechanism in the present system.…”

Gel chromatographic behavior of 8-hydroxyquinoline (oxine, abbreviated HOx) complexes of zinc, copper, aluminum, gallium and indium has been investigated on thin layers of Styragel 60A and Merckogel OR-PVA 2000 mostly in chloroform and p-dioxan media. Except for the stable Cu(Ox),, the other oxinates exhibit either hydration or decomposition in gel-solvent-solute systems, which leads to strong retention or tailing on gel layers. An excess of 8-hydroxyquinoline present in solvents allows the oxinates to be stabilized, so that well-defined compact spots come out and migrate. For the Zn(Ox)2 the formation of a selfadduct is strongly suggested on the basis of gel chromatographic behavior. Elution with the solvent containing pyridine also yields evidence of the adduct formation of zinc oxinatenitrogen base.
