Class Information
Number: 210/660
Name: Liquid purification or separation > Processes > Ion exchange or selective sorption
Description: Process in which the liquid is contacted with a solid insoluble material which (a) captures from the liquid a dissociated charged chemical moiety and releases to the liquid a different charged moiety of the same polarity by dissociation thereby effecting a chemical replacement reaction, (b) holds by attraction on its surface or within its pores a constituent dissolved or colloidally dispersed in the liquid, or (c) preferentially attracts one of two or more liquids in contact with each other.
