Ion Exchange Resins - Industrial Processes

 

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.
