Production of 88,89Zr by proton induced activation of natY and separation by SLX and LLX

Abstract

nat Y foil was irradiated by 20 MeV proton to produce no-carrier-added 88,89 Zr. A comparative evaluation on radioanalytical separation methods of 88,89 Zr was car- ried out from irradiated target matrix by both liquid-liquid (LLX) and solid-liquid (SLX) extraction methods using di-(2-ethylhexyl) phosphoric acid (HDEHP) dissolved in cyclohexane as liquid cation exchanger and Dowex 50W- X8 H ? form (20-50 mesh) as solid cation exchanger. Both the methods offer good separation and high yield of nca 88,89 Zr but SLX offers much higher separation factor and
