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
purification of biopharmaceuticals, nutraceuticals, pharmaceuticals, supplements (no FCN/FDA approval, batch related manufacturer’s declaration available, please inform technical sales person in case product is used for this application)
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).
