Ion exchange

Ion exchange (IEX) is a process that eliminates some or all of the ions (cations and/or anions) from a solution, replacing them with an equivalent number of other similarly charged ions. The process relies on ion exchange resins, generally in the form of synthetic micro-beads. When the resin has reached its exchange capacity, it can be regenerated by an acidic, basic, or salt solution.
