Abstract
Liquid-lquid extractive and UV-Vis spectrophotometric methods were attempted for
speciation analysis of chromium. To do this, some laboratory-synthesized ligands (isatinthiosemicarbazone,
dihydrazine ninhydrin and ninhydrin semicarbazone) and a
commercially available ligand, phenanthroline, ware used. There have been found that
they are inappropriate for both analytical applications. However, the chemical properties
may support some preconcentration or spectrophotometric applications. Suggestions for
these possible applications are therefore forwarded for future studies.
Key words: liquid-liquid extraction, Spectrophotometry, chromium speciation, Schiff’s
