reversible chemical reaction between a solid (the ion exchanger) and a water solution, by means of which ions may be interchanged from one substance to another.
An exchange of ions in a crystal with irons in a solution. Used as a method for recovering valuable metals, such as uranium, from solution
ion exchange resin; ion exchanger. Ion exchange is a method of separating ions from a solution by reversibly binding them onto a resin that has charged sites on its surface. Ion exchangers are used to remove metal ions from drinking water.
