ADSORBER RESIN AMBERLITE XAD-4 - Uses and methods of synthesis
Introduction
ion exchange resins are a class of functional polymers that can be exchanged with the same number of ions in aqueous solution. Is essentially a cross-linked polymer acid or polymer base. Phenolic type cation exchange resin was first developed in 1935, and industrial production began in Germany in 1939 and the United States in 1941. Polystyrene-based and poly-acrylic acid-based ion exchange resins were put into production after World War II. After 60 years, the development of macroporous ion exchange resin. According to the different exchange groups are divided into two types of cation and anion; According to the degree of ion dissociation difference is divided into strong acid, weak acid, strong alkaline and weak alkaline class. It can also be classified into gels, macropores, ion exchange membranes, and the like according to the appearance shape and physical properties. Also developed a chelating resin, Amphoteric resin, oxidation-reduction resin and other special varieties.
application field
Because of ion exchange resin with exchange, adsorption, catalysis, decolorization, dehydration, redox and other functions, and thus in electronics, electricity, metallurgy, chemical industry, atomic energy, medicine, light industry, environmental protection and other fields have been widely used. Such as softening hard water, desalination of seawater, preparation of high purity water, recovery of precious metals in wastewater, removal of radioactive substances in water, separation, concentration, purification and recovery of uranium, separation and purification of rare earth elements, precious metals, refined amino acids, antibiotics, vitamins, etc.
regeneration method
For example, for a strongly acidic cationic resin, a sodium hydroxide solution is introduced to remove impurity cations from the resin, and then a hydrochloric acid solution is introduced to reattach hydrogen ions to the resin. Studies have reported a kind of ion exchange resin regeneration method, the ion exchange resin includes cation exchange resin and anion exchange resin, the ion exchange resin regeneration method includes the following steps:
a). Washing the ion exchange resin with water through an ion exchange column containing the used ion exchange resin;
B), using the flow of the way to pass step (a) the treated ion exchange column is passed into the analytical solution to remove the impurity ions adsorbed or firmly bound on the ion exchange resin;
c), passing water into the ion exchange column treated in step (B) to remove the remaining solution on the ion exchange resin;
d) to the ion exchange column treated in step (c), a regeneration solution is introduced to restore the ion exchange capacity of the ion exchange resin;
e), passing water into the ion exchange column treated in step (d) to wash off the regeneration liquid remaining on the ion exchange resin;
