The Use of Synthetic Inorganic Ion Exchangers in the Removal of Cesium and Strontium Ions from Nuclear Waste Solutions Academic Article uri icon


  • Three pillared clays were prepared along with a sodium titanate and a sodium mica. These exchangers were examined for removal of Cs+ and Sr2+ in two types of groundwater and a highly alkaline tank waste (NCAW). Two zeolites were included for benchmark comparisons. The pillared clays showed a strong affinity for Cs+ in the groundwaters but not for Sr2+. Other synthesized exchangers exhibited high Sr2+ ion Kd values. The great variety, stability and specificity of inorganic ion exchangers requires that they be seriously considered for nuclear waste remediation.
