Abstract:	Summary 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 R_f values of the metal ions has been discussed in detail and a relationship between R_f and mole fraction (X) of the solvent has been obtained as R_f=mX+C. The usefulness of the study has been demonstrated by the specific extraction of titanium and thorium in HNO₃H₂O (12) and HNO₃:acetone:H₂O (161) systems. In addition, some binary and ternary separations of metal ions have also been achieved on these papers.
