Product Details

Lanlang ® TA301D Is a premium grade macroporous weak base anion exchange resin with polystyrene matrix and tertiary amine (Dimethylamine) function group in standard Gaussian size distribution. Its macroporous structure makes it can adsorb soluble organic molecules and can resist to osmotic & mechanical shock and oxidation. The weak base functionality makes TA301D could be regenerated easily even using waste caustic left from regeneration of strong base anion resin. So TA301D could be used multi bed demineralizers to prolong the lifetime of strong based anion resin and prevent it from organic fouling.
