LEWATIT® MonoPlus TP 209 XL

Summary

Product identification

LEWATIT® MonoPlus TP 209 XL is a weakly acidic, macroporous cation exchange resin with iminodiacetate (IDA) groups. It is designed for the selective extraction of heavy metal cations from weakly acidic to weakly basic solutions. This resin is particularly suited for concentration, extraction, and recovery of base metals in Resin-in-Pulp (RIP) processes due to its large bead size and high operational capacity.

The cation removal order is: Fe³⁺ > Cu²⁺ > VO₂²⁺ > UO₂²⁺ > Pb²⁺ > Ni²⁺ > Zn²⁺ > Cd²⁺ > Fe²⁺ > Mn²⁺ > Ca²⁺ > Mg²⁺ >> Na⁺.

Compared to LEWATIT® MonoPlus TP 207, LEWATIT® MonoPlus TP 209 XL offers:

• Lower dynamic pressure drop at the same flow rate
• Diminished risk of accumulation of suspended solids
• Easier screening and sieving during resin/feed separation
