Solid phase extraction of radioyttrium from irradiated strontium target using nanostructure ion imprinted polymer formed with 1-hydroxy-4-(prop-2-enyloxy)-9,10-anthraquinone.

A new complex of 1-hydroxy-4-(prop-2-enyloxy)-9,10-anthraquinone and Y(III) was synthesized and used as the functional monomer for a novel Y(III) nanostructure ion-imprinted polymer. This polymer was used as a sorbent for fast and selective separation. The separation method was based on radioyttrium sorption from aqueous HCl solution containing strontium onto ion-imprinted polymer. Influence of various parameters such as pH, mass sorbent, nature, concentration and volume of eluent was investigated. The radioyttrium recovery yield was 99.8% and Sr content was estimated to be 3 µg mL(-1).
