Ionivahetus
Ionivahetus, also known as ion exchange, is a chemical process used to remove undesirable ions from a solution and replace them with more desirable ions. This technique is widely employed in water purification, waste treatment, and various chemical manufacturing processes. The process operates through ion exchange resins, which are solid materials typically composed of organic polymers with functional groups capable of exchanging ions with the surrounding solution.
In ion exchange systems, the resins are pre-loaded with specific ions, such as sodium or hydrogen ions.
The advantages of ion exchange include high efficiency in removing a wide range of ionic contaminants, selectivity
Despite its effectiveness, ion exchange has limitations such as resin fouling and the need for regeneration
