Effect Of Temperature On The Association Constants Of Some Divalent Metal Ions With Chloride In Sea Water-Like Solutions, Jose Vinicio Macias Zamora
University of the Pacific Theses and Dissertations
Association constants for the formation of lead (II) chloride complexes were studies in aqueous solutions also containing copper (II) and cadmium (II) ions.
The ionic strength was adjusted with sodium perchlorate to resemble that of sea water. The temperature was set at fixed values between 5° and 35° C to determine the effect on the equilibria in these systems. The total metal concentration was less than 10-8 M.
Differential pulse anodic striping voltammetry was used with a conventional three electrode system and a thin-film working electrode of Pt/Hg. Complex formation was followed as a function of the ligand concentration …
