AB  - The complexation of the natural antioxidants alpha-lipoic acid (ALA) and its reduced form dihydrolipoic acid (DHLA) with Hg2+ was investigated by a recently proposed differential pulse voltammetric (DPV) method using the rotating Au-disk electrode. Complexation processes are proposed from the multivariate curve resolution by alternating least squares (MCR-ALS) analysis of DPV titration data. Main complexes were both 1:1 Hg: ALA and Hg: DHLA, although the formation of 1:2 complexes can be also deduced. ALA and DHLA show different Hg2+-binding patterns at different pH. Volta in metric findings are completed with the data obtained by electrospray ionization mass-spectrometry (ESI-MS), especially in negative mode.
