Description
Liquid-liquid distribution method was applied for the determination of the composition and stability constants of mercury species with L-cysteine (H2L). In the pH range 2-8, mercury(II) forms a complex Hg(HL)2 with very high stability constant, whereas methylmercury and phenylmercury form complexes CH3HgHL and C6H5HgHL. At pH>13, anionic complexes HgL22-, CH3HgL- and C6H5HgL are formed. (author) 9 refs
