摘要

HfO2样品通过分离纯化流程后

与NH4HF2进行固相反应制成HfF4

并用加速器质谱进行测量。结果表明:α-安息香肟萃取是降低182W含量的重要步骤;固相合成法制备的HfF4样品中180HfF5-的引出束流强度是同等条件下液相合成法的3-4倍;制样方法（固相合成法、液相合成法）对182W/Hf值影响不大;HfF4中182W/Hf值低至10-11g·g-1量级。

Abstract

The method of solid-phase synthesis of HfF4 for AMS measurement was researched in this paper.After separation and purification progress

the HfO2 sample was made to HfF4 which was measured by AMS with NH4HF2 by solid-phase reaction.The results show that the extraction of α-benzoin oxime was an important step for decreasing the 182W content.The beam flux of 180HfF5? in HfF4 made by solid-phase synthesis was three to four times higher than that made by liquid-phase synthesis at the same condition.The sample preparation methods(solid-phase synthesis or liquid-phase synthesis) have little impact on the ratio of 182W/Hf.The ratio of 182W/Hf in HfF4 was as low as 10?11 g·g?1.
