摘要：
The complexation of Co2+ and Ni2+ with N-(carboxymethyi)aspartic acid (CMA, H3X) was studied in aqueous solutions by pH titration at different ionic strengths (I = 0.1, 0.5, 1.0; KNO3). The formation of complexes MHX0, MX-, MX24-, and M(OH)X2- (M is Co or Ni) was established. The concentration and thermodynamic stability constants of the complexes were determined.
