D751 Macroporous Styrene Chelating Resin
For chemical applications( For heavy metal separation)
Macroporous iminodiacetate resin with highly selective for multi-valence metal ions. Used for separation and recovery of high valence metal ions & scarce metals and transition elements ions. When there are univalent and divalent metal ions only.The product is also suited to be used in getting rid of Ca2+ and Mg2+ ions in the salt electrolysis solution,in waste treatment.
