Summary
The efficiency of diantipyrilmethane used as a reagent for the chromatographic separation of metals, including titanium, zirconium and hafnium, rare earth elements, transition and platinum metals is shown. The peculiarities of the chromatographic behaviour of metal diantipyrilmethanates and the mechanism of their retention in TLC are discussed. Methods were developed for the determination of metals based on complex formation directly in the sorbent layer or by liquid extraction. The chromatographic separation takes place in silica gel thin layers with elution by organic solvent-mineral acid mixtures. The metals are determined by densitometric or spectrophotometric methods. After the complexes are isolated from the layer. The procedures are characterized by simplicity, efficiency, and a rather high selectivity. They were used to analyze steels, alloys, industrial solutions and other samples.
