Abstract

A number of ion exchange materials were modified and developed to remove specific radionuclides from waste solutions generated in the nuclear industry. Amongst the most promising materials developed were antimony silicates, metal doped antimony silicates, titanosilicates and manganese oxides. These materials have been provided the basis of a number of patent applications . The materials were first screened for the removal of a wide range of elements including radionuclides from 'model' waste solutions. Tests indicated that the materials performed very well in comparison with commercial reference materials such as clinoptilolite, silcotitanate and Na-titanate. The antimony silicates and metal doped antimony silicates were extremely effective in acidic solutions.

Further tests were carried out with simulated waste and groundwater solutions as well as real waste solutions from BNFL's Sellafield site. |The new materials were equal or superior in performance to the commercially available materials. .
