Purolite® A850
Gel Strong Base Anion Exchange Resin
Purolite A850 is a gel-type I strong base
anion exchange resin with an acrylic matrix.
The acrylic matrix ensures excellent removal
of organic matter from a water supply in
conjunction with its reversible removal
upon regeneration. This resin is regenerated
very efficiently with lower levels of sodium
hydroxide than those required for a polystyrene
based type I resin, and yet it has a comparable
ability to remove weaker acids including
carbonic acid and silica. Its use in combination
with a polystyrene based resin (for instance
in a mixed bed positioned after the anion
unit) can often result in the removal of
a wider spectrum of organic compounds than
either type of anion resin alone.
