Best Strong 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. 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.

Further information:

There are many ways to remove organic matter in water, one of which is the ion exchange method:

An ion in the treated solution migrates to the liquid film attached to the surface of the ion exchanger particles; it diffuses into the particles through the liquid film, and diffuses in the pores of the particles to reach the site of the ion exchange agent group; The ions are exchanged with the ions on the ion exchanger; the exchanged ions are transferred to the treated solution in the opposite way. The ion exchange reaction is completed instantaneously, and the speed of the exchange process mainly depends on the longest membrane diffusion or intra-particle diffusion.

Lanlang TA201D strong anion exchange resin can effectively remove organic matter in water.
