Abstract

In this work, hydrotalcites were used to remove131I from aqueous solutions. It was found that131I sorption by hydrotalcites depends greatly on the thermal treatment of the solid and does not take place by ion exchange as I is not capable of removing CO 3 −2 or other ions in the hydrotalcite. The anions have to be removed from the solid in order to permit I to be sorbed in the hydrotalcite. The radionuclide content was determined by γ-spectrometry and X-ray diffraction was used to identify the compounds and to estimate cell parameters.
