transition metal paper chromatography

  1. I have a vague memory of doing a chromatography of transition metal solutions on chromatography paper.

    Unfortunately this was 5 years and 2 different schools ago, so all I can remember for sure is that we developed the chromatograms in the fume cupboard and I think the development solution was conc. ammonia.

    Does anyone do this and has a method they are willing to share?

  2. Use a Mobile Phase (90% acetone, 10% 6 M HCl). Spot your samples and visulalise by placing the chromatogram in developing solvent (conc. NH3)
