Sažetak

A procedure for the quantitative estimation of Cd ions in
aq ueous solution, in the presence of other heavy-metal ions is
proposed. Separation of Cd is made by TLC, with a solvent system
containing acetic acid. The latter is necessary in order to obtain
Cd spots suitable for fluorescence scanning after the formation
of a fluorescent complex. Al ions cannot be separated from Cd
ions by this procedure. Therefore, the fluorescent cadmium complex
is generated with Titan Yellow, a reagent that does not react with
aluminum ions. The practical value of the procedure is, however,
limited by the narrowness of the useful Cd-concentration range.
