Chromatographic studies of metal complexes. Part VI. Investigation of the effect of electrolytes on thin-layer chromatography

  • Ranajit K. Ray

The octahedral cationic CoIII complexes [Co(ida)(bigH)2]+, [Co(glyO)(bigH)2]2+, [Co(α-alanO)(bigH)2]2+, [Co(β-alanO)BigH)2]2+ and Co(PhbigH)3]3+, where idaH2=iminodiacetic acid, glyOH=glycine, α-alanOH=α-alanine, β-alanOH=β-alanine and PhbigH=phenylbiguanide, were studied by thin-layer chromatography on silica gel in solutions of different electrolytes (NaCl, NaBr, NaI, Na2SO4, Na2S2O3, NaNO2 and NaNO3). Among other factors, the movement of the cationic complexes was found to be dependent on the surface tension and equivalent conductance of the developer electrolyte.
