前言分离富集铼常见的方法有蒸馏法、离子交换法、萃取分离法、液膜法、火试金法等[1-4]。传统的分离富集铼的方法虽然效率较高,但是步骤繁琐,试剂用量大,对环境造成很大的污染。1970年,Bowen等[5]首次用聚氨酯泡塑(以下称泡塑)从卤化物中吸附了汞、金、铁、锑、铊、铼和钼等金属离子。随后科研工作者对用泡塑吸附溶液中各种金属离子进行了广泛的研究,发现泡塑是吸附许多金属离子(如锡、 Preface separation and enrichment of rhenium common methods are distillation, ion exchange, extraction and separation methods, liquid film method, fire test gold method [1-4]. The traditional method of separation and enrichment of rhenium, though of high efficiency, is complicated in terms of steps, large amount of reagents and great environmental pollution. In 1970, Bowen et al [5], for the first time, adsorbed metal ions such as mercury, gold, iron, antimony, thallium, rhenium and molybdenum from a halide using polyurethane foam. Subsequent research workers using foam plastic adsorption solution of various metal ions were extensively studied and found that foam is adsorbed many metal ions (such as tin,
