The weak base anion exchange resins use either a polystyrene or polyacrylic ester frame and a primary-ternary amino group as the functional group. Although the anion of a salt like NaCl or Na2SO4 cannot be exchanged, the exchange of an anion of a mineral acid such as HCl and H2SO4, or the salt of a weak base like NH44Cl can be carried out.
Today let me recommend our TA301 weak base anion resin to you.It is a Macroporous weak base anion exchange resin, used for decoloration for sugar process.
Please check the following specification.
