Felite™ FS400 is a macroporous polystyrene-based chelating resin, with Iminodiacetic groups designed for the removal of cations of heavy metals from industrial effluents.

Felite™ FS400 finds use in processes for extraction and recovery of metals from ores, galvanic plating solutions, pickling baths, and effluents even in the presence of alkaline earth metals (calcium and magnesium). Further important uses include the refining of the salt solutions of transition and precious metals and for the cleaning and purification of various organic or inorganic chemical products by removal of heavy metals contamination (usually from aqueous solution).

Felite™ FS400 is supplied in both Industrial and Potable Water Grade.
