AMBERLITE™ Ion Exchange Resins
Weak Acid Cations and Chelating Resins - Sorted in alpha-numerical order
AMBERLITE™ polymer based weak acid ion exchange and chelating resins involve mostly the use of functionalized styrene divinylbenzene or polyacrylic copolymers with different surface properties and porosities. These resins are generally supplied as macroreticular spherical beads. Amberlite weak acid ion exchange resins are widely used for metals removal and recovery in mining and chemicals, ground water remediation, waste water treatment, and brine softening.
They have shown superior performance in many different applications. During
the development of these ion exchange resins the major focus was on high
selectivity, very low leakage, highest operating capacity, excellent regenerability
and lifetime.
