Model FC311 -Weak Acid Cation, Macroporous

FC311 is a premium grade polyacrylic weak acid cation exchanger. The functional groups of the carboxylic type give high chemical efficiency in many applications, especially for the removal of bicarbonate alkalinity in water treatment, showing good rates of exchange. 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. FC311 has also been used to selectively recover transition metals from aqueous solutions, or sugar treatment. FC311 is insoluble in acids, alkalies, and all common solvents. Weakly acidic cation resins are increasingly being used in special applications including treatment of waste water streams in order to reduce environmental pollution. FC311 is available in both Industrial Grade and Food Grade.
