Determination of the formation coefficients of Be-EDTA complexes

Abstract

The formation constants for four complexes of Be-EDTA with a metal to ligand ratio of 1:1 have been determined. The experimental procedure consisted in the radiometric determinations of the Be distribution coefficients on an ion exchanger in the presence and absence of EDTA. The formation quotients were calculated by an equation of Schubert modified in order to obtain the four quotients simultaneously and to correct for the sorption of a catión complex by the exchanger.The values obtained are critically discussed and compared with previous results listed in the literature.
