lon exchange is a powerful chemical technoloav through a reversible chemical reaction where dissolved ions are removed from solution and replaced with other ions of the same or similar electrical charae. lon exchange resin facilitates ion exchange reactions The resin itself is composed of organic polymers that forms a network of hvdrocarbons. and ion exchange sites. called"functional qroup" throughout the matrix The ion exchange sites attract ions of an opposina charge. which aive the ion exchange resin its separation capabilities

lon exchange resins are classified into cation exchange resins and anion exchange resins. as well as mixed bed ion exchange resins.The cation exchange resin can be exchanged with a cation, and the anion exchange resin can be exchanged with an anion. The mixed bedion exchange resin is a physical mixture of a positive resin and an anion resin, and at the same time removes anions and cations in the water.
