Description

Method of 89Sr separation from 89Y targets irradiated in fast reactor BR-10 is described. In the basis of this method is extraction chromatography. Strontium-specific material Sr Resin, which is di-tret-butyldicyclohexano-18-crown-6 immobilized on polymeric matrix, is used as solid extractant. Dissolution is carried out in 4-6 mol/l HNO3. Purification degree from radionuclides and inactive impurities permit to obtain radiopharmaceutical preparation

Abstract (Russian)

Описана технология выделения 89Sr из 89Y мишеней, облученных на быстром реакторе БР-10. В основу метода положен принцип экстракционной хроматографии. В качестве твердого экстрагента использовалась стронций-специфическая смола Sr Resin, которая представляет собой краун-эфир ди-трет-бутилдициклогексано-18-краун-6, иммобилизованный на полиакрилатной полимерной матрице. Степень очистки от радионуклидов и неактивных примесей позволяет получать фармпрепарат
