Abstract
The complexation of cadmium with aminoacids as glycine, alanine, L valine, serine and glutamic acid has been studied in seawater conditions (ionic strength 0.70 M NaClO4, t = 20 + 0.1°C). The stability constants have been determined by potentiometry and differential pulse polarography as complementary methods in order to check the accuracy. For all systems, with the exception of cadmium-glutamic acid complexes, a kinetic contribution was not noticeable in terms of differential pulse polarography, because the cadmium complexes were sufficiently labile and their equilibria sufficiently mobile with respect to the time scale of this technique.
