Polarographic studies of mixed hydroxy-complexes of monoethanolamine with cadmium and with lead.
The composition and stability of mixed complexes of cadmium or lead with hydroxide and monoethanolamine have been determined polarographically at 25 degrees in aqueous and aqueous methanol solutions at ionic strength 0.1M. For the aqueous solutions the results agree with those of others. In the methanolic systems the previously unreported complexes Cd(MEA)(4)(OH), Pb(MEA)(OH)(3), Pb(MEA)(2)(OH) and Pb(MEA)(2)(OH)(2) were detected.
