The sorption of144Ce(III) and of147Pm(III) on hydrated iron sesquioxide suspension and the sorption of144Ce(III) on hydrated iron sesquioxide in a laboratory column were studied. The dependence of the sorption on pH and time, the sorption isotherm, the temperature-dependence of sorption, and the effects of ionic strength on sorption and desorption were determined under static conditions. The maximum sorptions of144Ce(III) and147Pm(III) were reached at pH=7.4 (Kd=8.9·105) and pH=9.1 (Kd=6.2·105), respectively.
