چكيده لاتين :
In this study, the stability constant of dioxouranium with asparagine complexes and
protonation constant of asparagine at different ionic strength was investigatcd. Measurements have been
performed at 25°C, pH<3.5 and at ionic strengths ranging from 0.1 to 1.0 mol dmʹ sodium perchlorate,
using combination of potentiometric and spectrophotometric techniques. The composition of the formed
complexes and their stability constants were determined by cruve fitting method and it was shown that
dioxouraniurn forms two mononuclear 1:1 and 1:2 species in the form of U01(HL)1
1 and U02(HLh 2+.
The overall analysis of the present and the previous data dealing with the determination of stability
constant at different ionic strength allowed us to obtain a general equation by which the formation
constant determined at a fixed ionic strength can he calculated with a good approximation
