pH Adjusted, Heavy Metal Selective, Chelating Exchange Resin, Macroporous, Sodium Form
See DetailsResinTech SIR-300-pH adj. is a pH buffered form macroporous chelating weak acid cation resin. Its unique chelating functionality removes divalent transition metals preferentially to alkaline earth metals such as calcium. It is partially converted to the hydrogen form such that the initial effluent pH is slightly acidic rather than strongly alkaline. SIR-300-pH adj. is intended for the removal of low – moderate concentrations of heavy metals from waste streams.
