Purolite S930

Summary

Product identification

• Product name: PUROLITE® S930
• Product type: Chelating Resin
• Intended use: Chelating resin for copper removal

Application

Purolite S930 is a macroporous polystyrene-based chelating resin with iminodiacetic groups. It is designed for the removal of heavy metal cations from industrial effluents. This resin can separate these cations from high concentrations of univalent cations (e.g., sodium) and common divalent cations (e.g., calcium). Removal is effective in both weakly acidic and weakly basic solutions, depending on the target metals.

Specific applications include:

• Extraction and recovery of metals from ores.
• Galvanic plating solutions.
• Pickling baths.
• Effluents, even in the presence of alkaline earth metals (calcium and magnesium).
• Refining of salt solutions of transition and precious metals.
• Cleaning and purification of chemical products by removing heavy metal contamination from aqueous solutions.
