- Abstract
For the first time, the suitability of bismuth bulk rotating disk electrode (BiB-RDE) for the study of metal complexation has been tested. Cyclic (CV) and differential pulse (DPV) voltammetry have been used to study the complexation of Pb(II) with two of the most effective chelating agents for the treatment of Pb(II) poisoning ( meso-2,3-dimercaptosuccinic acid, DMSA, and 2,3-dimercapto-1-propanesulfonic acid, DMPS). Multivariate curve resolution has been applied to voltammetric data to obtain the stoichiometries and stability constants of the complexes formed. In both systems, the ML2 complex was predominant, with log β2 values of 10.13 and 8.80 for DMSA-Pb(II) and DMPS-Pb(II), respectively.
