Abstract

The state of trace concentrations of⁹⁵Zr–⁹⁵Nb and¹³⁴Cs was studied at an initial pH>13 in an uranyl triperoxidate medium using the electromigration method. OH^– ions governing the potential are adsorbed on the colloidal Nb(V)-hydroxide which leads to an increase in its negative electric charge; while⁹⁵Zr did not move during the procedure. However, the electrophoretic mobility of the¹³⁴Cs could be explained in terms of their agglomerations attributed to the interaction of Cs⁺ ions with water molecules to give larger aggregations.
