螯合树脂是带有螯合基团、对特定离子具有特殊选择性、有螯合分离能力的一类树脂。其选择性主要取决于功能基的性能。螯合树脂的应用范围及效果属一类分离提纯专用树脂。它既有生成离子键又有形成配价键的能力。在形成螯合物后,结构上好象螃蟹的螯钳,所以形象地叫螯合树脂(Chelate resin)。由人工设计并合成的多种多样的螯合树脂,多数是在邻近的位置带两种以上、起协合作用的功能基;对于带两种性质相反、起独立功能作用的树脂 Chelating resins are a class of resins with chelating groups that are selective for specific ions and chelating. Its selectivity depends mainly on the performance of the functional groups. Chelate resin applications and effects of a class of separation and purification of special resin. It has the ability to generate ionic bonds as well as the formation of valence bonds. After the formation of chelates, the structure is like a crab claw, so vividly called chelate resin (Chelate resin). Artificially designed and synthesized a wide range of chelating resins, mostly in the vicinity of the location with more than two, synergistic functional groups; with two opposite in nature, independent of the role of the resin
