LEWATIT® MonoPlus TP 260

Lewatit® MonoPlus TP 260 is a weakly acidic, macroporous cation exchange resin with chelating amino methyl phosphonic acid groups designed for the selective removal of heavy metal cations and alkaline earth cations.

The monodisperse, uniform sized beads of Lewatit® MonoPlus TP 260 are mechanically and osmotically more stable than ion exchange resin beds with heterodisperse bead size distribution. Additionally they offer superior kinetic behavior which leads to faster uptake of cations and a better utilization of capacity.

Due to its modified polymer structure and substitution grade it is for example suitable for use in:

• Fine polishing of brine fed to chloralkali membrane cells, e.g. by removal of Ca²', Mg²', Ba²', Sr²'; in the absence of Fei' 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 BF,- containing waste water out of PCB production
• Removal of iron(II), nickel and zinc from 5 % gluconate containing liquid metal working

Heavy metal and alkaline earth cations are removed out of neutralized process and waste waters in following order (decreasing affinity):
Uranium (U0₂²') > Lead > Copper > Zinc > Nickel > Cadmium > Cobalt » Calcium > Magnesium > Strontium > Barium >» Sodium.
