自1935年阿达姆斯(Adams)第一次合成离子交換树脂发表以后,二十余年来发展非常迅速。在类型上除已有的酚醛型、苯乙烯型、丙烯酸型等各种阴、阳离子交換树脂外,近年来尚有螯合型离子交換树脂、电子型交換树脂(或称氧化还原树脂)及蛇籠型树脂等。至于其品种形式方面亦由过去单一的粒状、球状树脂进展到离子交換膜、离子交換紙以及离子交換纤維等等。 Since the publication of Adams’ first synthetic ion exchange resin in 1935, it has developed rapidly for more than two decades. In addition to the existing types of phenolic, styrene, acrylic and other anion and cation exchange resin, in recent years, there are chelating ion exchange resin, electronic exchange resin (also known as redox resin) and snake cage Type resin and so on. As for the variety of forms from the past, a single granular, spherical resin progress to the ion exchange membrane, ion exchange paper and ion exchange fiber and so on.
