Lanlang ® TA201D Macroporous type I strong base anion exchange resin
Lanlang ® TA201D Is a premium grade macroporous type I strong base anion exchange resin with polystyrene matrix and quaternary amine (Trimethylamine) 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.
Water demineralization (deionization), organics removal.

TA201D in chloride form could remove both strong and weak acid radicals such as sulfate, nitrate, arsenate, chromate and silicate to extreme low concentration level. Combining with strong acid cation exchange resin (in hydrogen form), TA201D in hydroxide form can be used in all types of demineralization system especially be suited for high flow rate and high temperature polishing.
