Purolite S950
PDF datasheet mirror for Purolite S950 (Purolite). Verify with OEM before design.
Summary
Product Identification
- Product Name: PUROLITE® S950
- Product Type: Aminophosphonic Chelating Resin
Application
Designed for the removal of cations of toxic metals such as lead, copper, and zinc from industrial effluents, particularly at low pH. It also strongly complexes calcium, magnesium, barium, cadmium, nickel, and cobalt at higher pH values. It is more highly selective for a range of heavy metal and common divalent ions compared to iminodiacetic acid resins.

- Temperature Limit (Na⁺ form): 90 °C (195 °F)
- pH Stability: 0-14
- Operating pH (H⁺ form): 2-6
- Operating pH (Na⁺ form): 6-11
Typical Physical and Chemical Characteristics
- Polymer Structure: Macroporous crosslinked polymer
