We have recently proposed a simple scheme for identifying substances by means " of thin-layer chromatography by chromatographing with one (suitably chosen) solvent on several ready-for-use thin layers (usually four or five) thus obtaining more data with various supports than are obtained (evidently) with one single chromatogram. We were impressed by the fact that rather good identification was possible with some alkaloids and. dyestuff s as well as with amphetamines1 9%.
An obvious extension of this work was to investigate how inorganic ions would behave on various thin layers, It was soon realized that interaction with various supports can not compete with varying the solvent com.position e.g; the group Fe( ITI)-Co(II)-Ni( II) cannot be separated at low hydrochloric acid concentrations, whatever the support, while, at high hydrochloric acid concentrations many other metals are difficult to resolve. However, this first survey yielded a number of interesting results concerning the behaviour of heavy metal ions in a typical partition solvent (butanol-3 N HCl) on a wide range of ready-for-use thin layers.
