    Application
     
    1) Water treatment
    The demand for ion exchange resins in the field of water treatment is large, accounting for approximately 90% of the yield of ion exchange resins, and is used for the removal of various anions and cations in water. At present, the maximum consumption of ion-exchange resin is used for pure water treatment in thermal power plants, followed by atomic energy, semiconductors, and electronics industries.
    2) Pharmaceutical industry
    The ion exchange resin in the pharmaceutical industry plays an important role in the development of a new generation of antibiotics and in the improvement of the quality of the original antibiotics. The successful development of streptomycin is an outstanding example. In recent years, research has also been conducted on the aspects of traditional Chinese medicines and other aspects.
    3) Synthetic Chemistry and Petrochemical Industry
    Acids and bases are commonly used as catalysts in organic synthesis for esterification, hydrolysis, transesterification, hydration and other reactions. The use of ion-exchange resins in place of inorganic acids and bases can also perform the above reaction with more advantages. If the resin can be used repeatedly, the product can be easily separated, the reactor can not be corroded, the environment can not be polluted, and the reaction can be easily controlled.
    Methyl tert-butyl ether (MTBE) was prepared by using macroporous ion exchange resin as a catalyst and reacting isobutylene with methanol to replace the existing tetraethyl lead which could cause serious environmental pollution.
    4) Food Industry
    Ion exchange resins can be used in industrial equipment such as sugar, monosodium glutamate, wine refining, and biological products. For example, high-fructose syrup is produced by extracting starch from corn and then hydrolyzing it to produce glucose and fructose, which are then ion-exchanged to produce high fructose syrup. Ion exchange resin consumption in the food industry is second only to water treatment.
    5) Environmental Protection
    Ion exchange resins have been used in many environmental concerns. At present, many aqueous or non-aqueous solutions contain toxic ions or non-ionic substances that can be used for recycling. For example, the metal ions in the electroplating waste liquid are removed, and useful substances in the waste liquid of the film production are recovered.
    6) Hydrometallurgy and others
    Ion exchange resins can separate, concentrate, purify uranium and extract rare earth elements and precious metals from depleted uranium deposits.
     
     
    Storage
     
    Ion exchange resin can not be stored in the open air, and the storage temperature is 0-40°C. When the storage temperature is slightly lower than 0°C, the clarified saturated saline solution and the resin should be added into the packaging bag. In addition, when the storage temperature is too high, not only the resin is easily dehydrated, but also the degradation of the anion resin is accelerated. Once the resin loses water, it is not possible to add water directly when it is used. Soak it with clear, saturated salt solution, then gradually dilute with water, wash away salt, and keep it moist during storage.
