Kationimuuttajat
Kationimuuttajat, also known as cation exchangers, are materials that have the ability to exchange their cations with ions in a surrounding solution. These materials are typically solid and possess a charged network structure that holds mobile cations. When a solution containing other cations comes into contact with the cation exchanger, the mobile cations in the exchanger can be released and replaced by the cations from the solution. This process is reversible, meaning the exchanger can be regenerated by flushing it with a solution containing a high concentration of the original cations.
The effectiveness of a cation exchanger is determined by its capacity, which is the total number of
Cation exchangers have a wide range of applications. In water treatment, they are used to soften water
