The interaction of Eu with purified/protonized Aldrich humic acid (HA) was studied by the free liquid/moving boundary electrophoresis used in combination with the radiotracer method. Introductory experiments were carried out to test electrophoretic behavior of Eu in HA-free solutions, and to determine mobility of Eu 3+  cation. To get the data for evaluation of parameters describing Eu binding to HA, titrations of HA (10 mg/L) with Eu were performed batchwise in the range 3.4×10 -8 -1.7 -3  M of Eu total concentration at pH 3, 4, 5 and 6, and 0.01 M ionic strength (NaClO 4 ). In each batch, the degree of Eu complexation with HA was determined from  152 Eu electrophoretic mobilities in the cathodic direction. The experimental data were fitted with a discrete site model (Scatchard plot-like model) with two types of carboxylic sites. An additional information on the charge characteristics of the Eu-HA complexes has been obtained from the  152 Eu anodic mobilities.
