Purolite® A200
Gel Type II Strong Base Anion
Exchange Resin
Purolite A200 is a clear gel-type
strong-base anion exchanger containing Type-II
quaternary ammonium groups. It has excellent
operating capacity and good kinetics even
when regenerant levels are comparitively
low. It also rinses very efficiently after
regeneration. It shows good resistance to
physical and osmotic shock in normal operation.
It is particularly useful in treating feed-waters
with a high proportion of Free Mineral Acidity,
and in addition it has high reversible sorptive
capacity for the complex organic materials,
both ionised and un-ionised, which occur
in many surface water supplies. Specially
tailored size grades may be used with excellent
results in most of the usual ion-exchange
column configurations, but they are particularly
suitable for deionizing waters in counter-flow
operation, where, rinse volumes represent
a marked improvement over those of the classical
Type-II, Purolite A300, for example. In
a conventional two-stage deionizing plant,
its silica-removal properties are comparable
with those of any premium Type-II strong-base
anion exchanger; however, as with other
resins of this type, a polishing mixed-bed
is necessary to ensure the lowest levels
of residual silica. Like all type-II resins,
it is not recommended to expose the hydroxide
from of the resin to temperatures above
40o C. This results in gradual loss of strong
base functionality.
