Potentiometric studies on the complex formation between methylmercury(II) and some keto- and amino-carboxylic acids.
The protonation of pyruvic and laevulinic acid, l-serine, l-cysteine, l-methionine and l-asparagine, and their complex formation with methylmercury(II) ions, have been studied by a potentiometric method, in 1.0M sodium nitrate medium at 25 degrees . The protonation and equilibrium constants were evaluated by using the computer program LETAGROP-ETITR. The limitations of the experimental method are explained. The participation of different functional groups of the ligands in binding methylmercury(II) and the biological significance of the complex formation are discussed.
