Abstract
Cr(III) + phenanthroline complexes were Prepared under different pH an d concentration conditions. The presence of hydroxylated species in so lution was detected by studying the transference of the complexes thro ugh the water-1,2-dichloroethane interface. Voltammetric analysis, whi ch includes variation of I-p and E(p) with pH and concentration and th e calculation of the Gibbs energies of transference, enabled the speci es transferred to be identified. The advantages of this method over vi sible and UV spectroscopy are also discussed.
