Summary
Product identification
PUROLITE® S957 is a Chelating Resin for Ferric Iron removal.
Application
Purolite S957 is a specially developed Monophos chelating resin designed for the selective removal of ferric iron from acidic solutions, such as copper electrolyte or from nickel, cobalt, and zinc processing solutions. It can also be used in potable water applications for the selective removal of trace levels of selected metals from neutral pH waters. Its selectivity for uranium and other lanthanide elements may offer opportunities in other areas.
