摘要：

The equilibrium constants for the protonation of lactobionic acid (4-O-beta-D-galactopyranosylgluconic acid) and its co-ordination with Fe(III) were studied by potentiometric methods in aqueous solution, at 20.0-degrees-C and I = 0.1 00 mol dm-3 (NaNO3). The equilibrium data were processed with the Fortran computer program BEST. Correlations of chelate hydrolysis constants with those of the D-gluconic acid-iron(III) system were carried out. Co-ordination bonding sites and stereochemistry of metal-ligand interactions were inferred from UV and NMR spectroscopy.
