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).

Targetry of SrCO(3) on a copper substrate by sedimentation method for the cyclotron production no-carrier-added (86)Y.

Strontium carbonate deposition on copper substrate was carried out by the sedimentation method in order to produce yttrium-86. Natural strontium carbonate thick layer was prepared with 480 mg SrCO(3), 220 mg ethyl cellulose, and 7.5 mL acetone. This optimum condition is a result of several repeated experiments with different amount of ethyl cellulose and acetone. Target quality control was done by SEM photomicrograph and thermal shock test. The deposited target was irradiated at 30 microA current and 15 MeV proton beam for 12 min.
