Abstract

The polarographic method has been applied to the study of the mixed-coordinated system Pb(II)-alanine-alaninate ion in aqueous medium, <i>I</i> = 1.0 mol l<sup>-1</sup> (NaClO<sub>4</sub>) and 25 ± 0.1°C. The formation of the complexes [PbA]<sup>2+</sup> (β<sub>10</sub> = 13.2), [PbA<sub>2</sub>]<sup>2+</sup> (β<sub>20</sub> = 25), [PbA(A<sup>-</sup>)]<sup>+</sup> (β<sub>11</sub> = 1.01 . 10<sup>5</sup>), [Pb(A<sup>-</sup>)]<sup>+</sup> (β<sub>01</sub> = 3.76 . 10<sup>4</sup>) and [Pb(A<sup>-</sup>)<sub>2</sub>] (β<sub>02</sub> = 6.74 . 10<sup>7</sup>) was observed.
