Product Description
According to the nature of the exchange groups, ion exchange resins can be divided into two categories: cation exchange resins and anion exchange resins.
Cation exchange resins mostly contain acidic groups such as sulfonic acid group (-SO3H), carboxyl group (-COOH) or pheno group (-C6H4OH), among which hydrogen ions can be exchanged with metal ions or other cations in solution. For example, a polymer of styrene and divinylbenzene is sulfonated to obtain a strongly acidic cation exchange resin. Its structural formula can be simply expressed as R-SO3H, where R represents the resin matrix, and its exchange principle is
2R-SO3H + Ca2 + (R-SO3 ) 2Ca + 2H +
This is also the principle of hard water softening.
The anion exchange resin contains basic groups such as quaternary amine group [-N (CH3) 3OH], amine group (-NH2) or imine group (-NH2). They can generate OH- ions in water, which can exchange with various anions. The principle of exchange is
R-N (CH3) 3OH + Cl- R-N (CH3) 3Cl + OH-
because the ion exchange is reversible, so used Ion exchange resin is generally washed with an appropriate concentration of an inorganic acid or alkali, and can be restored to its original state and reused. This process is called regeneration. Cation exchange resin can be rinsed with dilute hydrochlor acid, dilute sulfuric acid and other solutions.
Ion exchange resins have a wide range of uses, mainly for separation and purification. For example, it is used to soften and produce deionized water, recover metals from industrial wastewater, separate rare and precious metals, and isolate and purify antibiotics.
