ASB 8020D

Strong Base Anion Exchange Resin Type-II

DOSHION ASB-8020D is a Macroporous, Type-II Strong Base Anion Exchange Resin. It is based on polystyrene matrix with quatemary ammonium Type-II functional groups. Its special properties include the ability to remove a large percentage of organic matter that may be present. The macroporous structure permits the regenerant solution to reach the sites of the organic debris and remove it. This resin is recommended when (silica + COO /total anion ratio is less than 30%; if the (silica + COO/total anion ratio is more than 30%, ASB-8010D is recommended.
