【摘要】 置换色谱法是一种较有优势的氢同位素分离方法,而分离材料的性能是决定置换色谱法分离效果的一个关键因素。目前研究的置换色谱分离材料包括钯材料和很多非钯材料。钯虽然价格昂贵,但由于其出色的分离性能而难以用廉价金属或合金来替代。本文简要介绍了置换色谱法分离氢同位素的原理,重点介绍了几种置换色谱含钯分离材料(纯钯、载钯硅藻土、载钯氧化铝、钯铂合金等)的性能,初步分析了置换色谱分离材料的发展方向。更多还原

【Abstract】 Displacement chromatography(DC) is a ascendant technique for hydrogen isotopes separation.The performance of separation materials is a key factor to determine the separation effect of DC.At present,kinds of materials are researched,including palladium materials and non-palladium materials.It is hardly replaceable because of its excellent separation performance,although palladium is expensive.The theory of hydrogen isotopes separation using DC was introduced at a brief manner,while several palladium separation materials were expatiated in detail(Pd/K,Pd-Al2O3,Pd-Pt alloy).Development direction of separation materials for DC was forecasted elementarily.更多还原
