TEWARI, Brij B. INTERACTION OF (AMINOBUTENOIC ACID WITH DIVALENT BERYLLIUM(II) AND COBALT(II) IN CHEMICAL AND BIOLOGICAL SYSTEMS. Rev. Bol. Quim [online]. 2010, vol.27, n.1, pp.7-12. ISSN 0250-5460.

ABSTRACT Paper electrophoresis has been applied to the study of metal complexes in solution and attempts have been made to determine the stability constants of complex species.  The proportion of ionic species of (-aminobutenoic acid was varied by changing the pH of background electrolyte.  The stability constants of ML and ML2 complexes of Be(II) - (-aminobutenoic and Co(II) - (-aminobutenoic acid complexes were found to be (7.19 ± 0.09, 5.91 ± 0.11) and (4.19 ± 0.03, 3.57 ± 0.07)  (logarithm stability constant values), respectively at ionic strength 0.1 Mol L-1 and a temperature of 35° C.
