Hot sale strong base anion exchange resin
Firstly, ion exchange resins can be divided into two major categories of cationic resins and anionic resins, which can be ion exchanged with cations and anions in solution, respectively.
Anionic resins can be divided into two types: strong base and weakly base.
The TA213D we mentioned below belongs to strong base anion resin.
Adsorption of anions
The general order of adsorption of inorganic acid radicals by SBA resins is:
SO42-> NO3- > Cl- > HCO3- > OH-
TA213D is a high quality and hot sale product.
Its appearance is white opaque, spherical beads.
New resin pretreatment
Industrial products often contain small amounts of oligomers and monomers that do not participate in the reaction, and also contain inorganic impurities such as iron, lead, and copper. When the resin comes into contact with water, acid, alkali or other solutions, the above substances are transferred to the solution, affecting the quality of the effluent. Therefore, the new products must be pretreated before use. Generally, the resin is first expanded with water, and then the inorganic impurities (mainly iron compounds) can be removed with 4-5% dilute hydrochloric acid, and the organic impurities can be removed by using 2-4% dilute sodium hydroxide solution to near neutral.
