Abstract

The reactions of N-(carboxymethyl)aspartic (H3Y) and N,N-bis(carboxymethyl)aspartic (H4X) acids with Pb2+ ions were studied by potentiometric titration at 298.15 K and I = 0.2, 0.5, and 1.0 (KNO3). The formation of complex species PbY−, PbHX−, and PbX2− was found and their stability constants were calculated.
