Exchange resin knowledge

1. The more charge an ion carries, the simpler it is to be attached to the anion exchange resin. For example, divalent ions are more easily adsorbed than monovalent ions.

2. For ions with the same charge, ions with larger atomic numbers are more easily adsorbed.

3. Compared to dilute solutions, low valence ions in concentrated solutions are more likely to be attached to the resin. Generally speaking, for H-type strong acidic cation anion exchange resin, the selection order of ions in water is important. For OH type strong alkaline anion exchange resin, the selection order of anions in water. The selectivity of anion exchange resin is very useful for analyzing and distinguishing chemical water treatment processes.
