Abstract

1. The polarographic behaviour of glycine, α-alanine, β-alanine, valine, aspartic acid, glutamic acid and asparagine complexes of lead has been studied at various pH values and in presence of (1) NaOH, (2) Na2CO3 and (3) NH4 NO3+NH4OH. All the polarographic waves have been found to be reversible. 2. Experiments conducted on the effect of variation of pH, i.e., 7<pH<9 (varying slightly in different cases), on half-wave potential keeping the total concentration of amino-acid have indicated the formation of Pb A and Pb A2. The data have been analysed employing the equations developed by DeFord and Hume as modified by McKenzie and Mellor. 3. Only pure complexes are produced below pH 11·2 in the case of aspartic acid, glutamic acid and glycine, ...
