A systematic study of the chromatography of metal ions on stannic tungstate papers has been performed using acetone-HNO3−H2O systems. The effect of mole fractions of acetone, HNO3 and H2O on the Rf values of the metal ions has been discussed in detail and a relationship between Rf and mole fraction (X) of the solvent has been obtained as Rf=mX+C. The usefulness of the study has been demonstrated by the specific extraction of titanium and thorium in HNO3∶H2O (1∶2) and HNO3:acetone:H2O (1∶6∶1) systems. In addition, some binary and ternary separations of metal ions have also been achieved on these papers.
