ABSTRACT
The thermodynamic constants of the complex Cu(II)-dopamine in aqueous solution were evaluated from spectrophotometric data using the software SQUAD. It was found that there exist Cu(II):DA complexes with 1:1 and 1:2 stoichiometries and that their predominance depends on both the solution pH and the [Cu(II)]/[DA] ratio. Moreover, it is shown that the solubility of Cu(OH)2(s) increases drastically when these complexes are thermodynamically stable.
