Complex-forming equilibria in isotachophoresis : IV. Simulation of isotachophoretic equilibria of metal ions forming multi-coordinated complexes

摘要: Abstract A computational procedure is given for the qualitative analysis of isotachophoretic equilibria metal ions forming labile multi-coordinated complexes with counter ions. For zinc-α-hydroxyisobutyrate system, index RE Zn2+ was simulated at pH  4.4 by varying coordination numbers (1–3) and stability constants concentration leading ion, CtL. Different dependences values on (fx219-2)CtL were obtained differently coordinated complexes, suggesting that can be evaluated from observed least squares method. The present method applicable to mixed different numbers.
