A835, Weak Base Anion Exchange Resin
Purolite® A835, Weak Base Anion Exchange Resin is a macroporous-type anion exchange resin with an acrylic matrix. The macroporous acrylic matrix ensures excellent removal of organic acids including those of high molecular weight from process liquors. The desorption which occurs upon regeneration markedly reduces the risk of resin fouling, thus maintaining the high operating capacity. Purolite A835 is regenerated very efficiently with lower levels of sodium hydroxide than those required for an equivalent polystyrene based resin. 110-120% of the stoichiometric quantity is usually sufficient. The tough resilient macroporous structure affords excellent mechanical strength and resistance to osmotic shock. The higher than average basicity offers advantages in removal of a wider range of more weakly acidic materials in many special applications.
