分离提纯是离子交换树脂的一个重要的应用方面。人类无穷、资源有限,生活的提高、环境的保护都需要具有特殊选择性的树脂。树脂的选择性主要取决于功能基,骨架母体的作用并不很大。一般阴阳树脂对不同离子虽然也有不同的选择性,但很难用于高度分离提纯。树脂的使用是要求在良好的骨架基础上带有特殊结构的功能基并通过功能基的络合作用达到专一选择性结合的目的,然后再改变条件,解吸分离。
Separation and purification of ion exchange resin is an important application. Human infinite, limited resources, improve living, environmental protection requires a special selective resin. The selectivity of the resin depends mainly on the functional group, the role of matrix backbone is not large. Although different yin and yang resins have different selectivity to different ions, they are difficult to be used for highly separated and purified. The use of resin is required in the framework of a good skeleton with a special structure of functional groups and functional groups through the complex to achieve the purpose of selective and selective integration, and then change the conditions, desorption separation.
