Lewatit® FO 36 is a macroporous, monodispersed, weakly basic, polystyrene-based ion exchange resin for the selective adsorption of oxoanions, such as arsenate or arsenite ions. It is doped with a nano-scale film of iron oxide covering the inner surfaces of the pores of the polymer bead. Target oxoanions are bonded by a specific, reversible reaction involving hydroxy-groups on the iron oxide surface.
Lewatit® FO 36 is especially suitable for use in the following applications:
In the purification of potable water arsenic can be removed down to rest concentrations significantly lower than 10 µ g/l which is the maximum contaminant level set in several countries. Lewatit® FO 36 is also capable of adsorbing other species such as HPO 4 2-, HSbO4 2-, SCN- etc.
