The composition of the complexes formed in the systems V(III)-complexone was studied by spectrophotometric and pH-metric methods; Kinst of V(III) complexonates were calculated.
The kinetics of the oxidation of V(III) by ClO 4 − ions in the presence of ethylenediaminetetraacetic acid (EDTA) and diethylenetriaminepentaacetic acid (DTPA), was studied. In the presence of DTPA, there is less stabilization of V (III) with respect to the ClO 4 − ion than in the presence of EDTA.
