摘要：

The polarographic method has been used to the study of the systems Pb(II)-valine and Pb( II)-valinate ion in aqueous medium, at I = 0.15 mol l(-1) (NaClO4) and 37 degreesC. The stabilized complexes were found: [Pb(HV)](2+), beta(10) = 9.0; [Pb(HV)(2)](2+), beta(20) = 12; [Pb(V)](+), beta(01) = 1.8 x10(4); and [Pb(V)(2)], beta(02) =1.7 x 10(6).
