Selective extraction of naturally occurring radioactive Ra2+ from aqueous waste streams : extractants based on thiacalix4arene and (iso)guanosine

摘要

This thesis describes the design and selectivity of new Ra2+ extractants. The results presented provide insight in both the requirements needed to give Ra2+ selectivity and in the achievable Ra2+/Mn+ (Mn+ = alkali(ne earth) cation) separations.
