The weak base anion exchange resins use either a polystyrene or polyacrylic ester frame and a primary-ternary amino group as the functional group.
Today let me recommend you Lanlang TA312 Weak base anion resin to you. Used for water deacidification and decolorization.
Lanlang ® TA312 is a premium grade gel type weak base anion exchange resin with acrylic matrix and tertiary amine (Dimethylamine) function group in standard Gaussian size distribution.
The acrylic matrix has excellent effectiveness for adsorption and desorption of organic molecules. TA312 also has very high free base capacity. TA312 is recommended to be used for deacidification and decolorization where the longest life time is needed (such as for single cartridge uses), especially for water with high organics.
