Ionic Strength Dependence of Formation Constants, Protonation and Complexation of Proline with Dioxovanadium(V)

Abstract

The stability constants of dioxovanadium(V) complexes of L-proline at different ionic strengths ranging from 0.1 to 0.7 mol dm^-3 at 25 ºC were determined using spectrophometric technique. The parameters based on the formation constants were calculated and the dependence of protonation and the stability constants on ionic strength were described by a Debye-Huckel type equation.
