Концентрационные и термодинамические характеристики комплексообразования Al3+ с этилендиамин-n,n'-диянтарной кислотой в водных растворах
2011
The complexation of Al 3+ with ethylenediamine-N, N`-disuccinic acid (H4L) was studied by potentiometric methods and mathematical modeling at 25 oC on a background of 0.1, 0.5, 1.0 M solutions of KNO3. Thermodynamic constants of complexes AlL, AlHL were calculated by extrapolating the concentration constants to zero ionic strength according to the equation with one individual parameter values. Their logarithms are 16.27 ± 0.07 and 9.19 ± 0.2, respectively.
