Summary

The chromatographic behaviour of some metal ions on silica gel thin layers has been studied in aqueous formic acid and mixed aqueous-organic solvent systems containing formic acid. Many analytically important separations of cations have been achieved in varying concentrations of formic acid solution in DMSO, acetone, and methyl ethyl ketone. Semiquantitative determination of nine cations has also been attempted.

The most suitable concentration range of acid for reliable and reproducible separations was found to be 0.1M to 1.0M.
