LEWATIT® MonoPlus TP 207

Lewatit® MonoPlus TP 207 is a weakly acidic, macroporous cation exchange resin with chelating iminodiaceticacid groups designed for the selective extraction of heavy metal cations from weakly acidic to weakly basic solutions. Divalent cations are removed from neutralized waters in the following order (decreasing affinity):


Copper > Vanadium (V02') > Uranium (U0221 > Lead > Nickel > Zinc > Cadmium > Cobalt > Iron (II) > Beryllium > Manganese » Calcium > Magnesium > Strontium > Barium >>> Sodium.


The monodisperse, uniform sized beads of Lewatit® MonoPlus TP 207 are mechanically and osmotically more stable than ion exchange resin beads with heterodisperse bead size distribution. Additionally they offer superior kinetic behavior which leads to faster uptake of cations and a better utilization of capacity. Therefore it is suitable for use in the following applications:

 

  • the selective removal of metal contaminants from processing baths
  • the concentration, extraction and recovery or heavy metals from hydrometallurgical solutions
  • the recovery of useful metals from electroplating rinse waters
  • the selective trace removal of heavy metals from industrial metal surface finishing effluents, even in presence of high calcium concentrations
  • the selective removal of heavy metals out of contaminated ground and waste water streams for potable water production and ground water remediation


The selective extraction of heavy metal cations by Lewatit® MonoPlus TP 207 is also achieved in presence of complexing agents such as nitrogen compounds (e.g. ammonia, aliphatic and aromatic amines), multivalent carboxylic acids (e.g. citric, gluconic, tartaric, oxalic acid) and phosphates (e.g. sodium polyphosphate, tetrasodium diphosphate).
