LEWATIT® MonoPlus TP 214

Lewatit® MonoPlus TP 214 is a macroporous resin with chelating thiourea groups designed for the selective removal of mercury, precious metals of the platinum group, gold and silver.
Cations are removed from neutral solutions in the following order (decreasing affinity):
Hg2+ > Ag+ > Au+/3+ > Pt2+/4+ > Cu2+ > Pb2+/4+ > Bi2+ > Sn2+ Zn2+ > Cd2+ > Ni2+
The monodisperse, uniform sized beads of Lewatit® MonoPlus TP 214 are mechanically and osmotically more stable than ion exchange beds with a heterodisperse bead size distribution. Additionally they offer superior kinetic behavior which leads to faster uptake of cations and a better utilization of capacity (up to 100 gHg/L of resin). Also it offers a remarkable low leakage according to the process conditions (low ppb range). Due to its excellent affinity and adsorption capacity Lewatit® MonoPlus TP 214 is especially suitable for:

  • The removal of mercury (Hg) in flue gas scrubbing processes

  • Fine polishing of brine fed to chloralkali membrane cells in plants using

  • Mercury process and within conversion to membrane process

  • The removal of mercury from ground water

  • Metal separation and recovery in hydrometallurgy, e.g. for gold (Au), silver (Ag) and platinum metals (Pt, Pd, Ru, Rh)

  • The recovery of platinum group metals from rinse water and exhausted process solutions

  • Recovery of palladium catalysts from organic process streams


A significant benefit is the resins odorless property which allows safe filling of filters.
The regeneration of Lewatit® MonoPlus TP 214 is not possible with usually applied regenerant solutions. Incineration of resin is recommended either in order to recover precious metals or to dispose of mercury in accordance with the local regulations.
