AmberSep IRC747 UPS Chelating Resin is a uniform particle size resin of macroporous structure. Its polystyrenic matrix, crosslinked with divinylbenzene, contains amino-phosphonic groups. The chemical nature of these groups is such that they form complexes with metal ions. The narrow particle size distribution affords an exceptional pressure drop profile.
AmberSep IRC747 UPS features very high operating capacity for calcium and is especially useful when treating brines that do not have a very high strontium content. Under these conditions, the resin offers an improved cycle time, displaying also very good removal efficiency for barium and strontium.
AmberSep IRC747 UPS is also used for metal recovery in hydrometallurgical applications.
