Sorption of Radionuclides by Surface Coatings

Abstract

Radionuclides ¡Radioactive contamination /Sorption /Surface coatings SummaryThe sorption of radionuclides by painted surfaces from aqueous solutions of different pH has been measured by an immersion technique at 298.2 K. This approach has distinct advantages over decontamination procedures used previously. The sorption of a metal-ion species is related to its basicity ; the charges on radiocolloids and on the surface coating are also of consequence. Results are presented for the take-up of radioactive caesium, cobalt, hafnium, scandium, and zinc by epoxide, urethane, and chlorinated rubber paints.
