虽然离子交换树脂中离子的结构是非常重要的，但由于缺乏有效的方法，研究报道很少。X射线吸收精细结构是研究离子交换过程中涉及的结构方面最有效的工具之一，因为它对感兴趣的元素具有高度的选择性，并且适用于任何材料和相。用这种方法讨论了阴离子交换树脂Cl-和Br2-的结构，比较了干燥树脂和浸泡在溶剂中的树脂的结构，揭示了离子交换基团和溶剂的影响。
Although the structures of ions in ion-exchange resins are of fundamental importance, very few studies have been reported because of the lack of efficient approaches. X-ray absorption fine structure is one of the most efficient tools for studying structural aspects involved in ion-exchange processes because it is highly selective to an element of interest and is applicable to any materials and phases. The structures of Cl- and Br- an anion-exchange resin are discussed by this approach; the structures both in dry resins and in resins soaked in solvents are compared to reveal the effects of ion-exchange groups and solvents.
