LEWATIT® MonoPlus TP 260

Summary

Product identification

Lewatit® MonoPlus TP 260 is a weakly acidic, macroporous cation exchange resin with chelating aminomethyl phosphonic acid groups.

It is designed for the selective removal of heavy metal cations and alkaline earth cations. The resin features monodisperse, uniform sized beads.

Common Description:

• Delivery form: Na⁺
• Functional group: Aminomethylphosphonic acid
• Matrix: Styrenic
• Structure: Macroporous
• Appearance: Beige, opaque

Operating limits

• Stability pH range: 0-14
• Stability temperature range: 1-80 °C
• Storage temperature range: -20 - +40 °C
• Operating temperature: max. 80 °C
• Operating pH range during exhaustion: 1-12

Feed water

The resin is suitable for various applications including:

• Fine polishing of brine fed to chloralkali membrane cells (removal of Ca²⁺, Mg²⁺, Ba²⁺, Sr²⁺ in the absence of Fe³⁺ ions).
• Fluoride (F⁻) removal using aluminum (Al) doped Lewatit® MonoPlus TP 260.
• Antimony (Sb) and bismuth (Bi) removal from copper containing electrolyte.
• Uranium (U) removal from crude phosphoric acid.
• Titanium (Ti) removal from recycled battery acid.
• Aluminum (Al) removal from urea solutions.
• Lead (Pb) and strontium (Sr) removal from BF₄⁻ containing wastewater out of PCB production.
• Removal of iron(II), nickel, and zinc from 5 % gluconate containing liquid metal working solutions.

Heavy metal and alkaline earth cations are removed in the following order of decreasing affinity: Uranium (UO₂²⁺) > Lead > Copper > Zinc > Nickel > Cadmium > Cobalt >> Calcium > Magnesium > Strontium > Barium >>> Sodium.
