EspañolProduct overview
ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange.
It is an insoluble matrix normally in the form of small microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
The beads are typically porous, providing a large surface area on and inside them where the trapping of ions occurs along with the accompanying release of other ions, and thus the process is called ion exchange.
Applications
Water treatment In the field of water treatment, the demand for ion exchange resin is very large, accounting for about 90% of the output of ion exchange resin, which is used for the removal of various anions and cations in water. At present, the largest consumption of ion exchange resin is used in pure water treatment in thermal power plants, followed by atomic energy, semiconductor, and electronics industries.
The ion exchange resin in the food industry can be used in industrial devices such as.
