Industrial Grade, Weak Acid Cation Resin, Macroporous

Macroporous Weak Acid Cation Resin Felite

DESCRIPTION:

Felite FC311 is a porous-type polyacrylic weak acid cation exchange resin with standard mesh size. Its carboxylic type functional groups give high chemical efficiency in many applications, especially for the removal of bicarbonate alkalinity in water treatment. Its major use is in the dealkalization and softening of waters and thereby the ionic load on the subsequent strong acid resin bed can be reduced. 

Felite FC311 product has also been used to selectively recover transition metals from aqueous solutions.
