一、应用离子交换树脂作为反应试剂的历史发展最近三十年来,离子交换树脂在化学上的应用发展得很快。现在不仅在分离和浓集方面用得很广泛;在分析方面的应用也日渐增多。在1942年,盖的斯(S.Gaddis)以阴离子交换树脂和硫化氢饱和水溶液进行交换后,用来作阳离子的沉淀剂。十余年以后,(氵龟)山和水渡曾用不同类型的离子交换树脂在柱上以氯化物、硫化物、氢氧化物、碳酸盐等形式,分离常见元素所形成的阳离子。科勃梁斯基(А.Г.Коблянский)曾在离子交换树脂表面进行了显微结晶分析。垣花、村濑以及藤本昌利等,在树脂点滴试验上作了许多工作,他们的一部分试验中,是把离子交换树脂浸入试剂以后,再用来进行点滴试验。密勒(W.E.Miller)曾试用各种不同类型交换基(包括无机物和有机物)的离子交换树脂以发生反应,以后并应用于固体指示剂。在上项工作的历史发展中,作者注意到了二个问 First, the application of ion exchange resin as a reaction reagent in the history of the past three decades, ion exchange resins in the chemical application of the development of very fast. Not only is it now widely used in separation and concentration, but also in analytical applications. In 1942, S. Gaddis was used as a cation precipitant after it was exchanged with an anion exchange resin and a saturated aqueous hydrogen sulphide solution. More than a decade later, different types of ion exchange resins were used in the mountain and water diversion to isolate cations formed by common elements in the form of chlorides, sulfides, hydroxides, carbonates and the like. А.Г. Коблянский had a microscopic crystal analysis on the surface of ion exchange resins. In the flower, Murase and Fujimori changli, etc., in the resin drip test done a lot of work, part of their experiment, the ion exchange resin is immersed in reagents, and then used for drop test. W.E. Miller has experimented with ion exchange resins of various types of exchange groups, including inorganic and organic substances, to react and thereafter apply to solid indicators. In the historical development of the above work, the author noticed two questions
