capillary electrophoresis - Opis:
- In the present work, we investigated the ability of electrophoresis to determine the stability constant of the complex formed between lactate ions (a simple model of natural organic matter), and lanthanum (III) and europium (III), two model metal cations of actinides. The effect of lactate on lanthanide’s effective mobility is studied, and conditional metal ion-ligand interaction constants are determined on the basis of the variation in the effective mobilities (log βn = 2.23 for lanthanum (III) and 2.39 for europium (III), at 25°C and I=0.015 M). The originality of this contribution lies in the fact that we have chosen to detect the metal ion instead of the ligand by an indirect UV-visible detection and using a chromophoric compound (creatinine).
