Short description: A procedure using the limiting currents of a titration experiment to compute the binding curve of the labile complexes formed with a metal and a heterogeneous ligand is presented. The binding curve so obtained is used in an iterative procedure to improve the computation of the fraction of free metal in bulk conditions at each metal-to-ligand ratio up to convergence. The resulting process constitutes a rigorous way to obtain the binding curve. Its application to some cases with discrete or continuous affinity spectra is presented.
