Weak Acid Cation Series

CR 2012 Weak Acid Cation

Aldex CR 2012 is an extreamly durable macroporous resin containing aminomethyl phosphonic group attached to polystyrene copolymer matrix. Aldex CR 2012 is used for selective removal of bivalent metal cations from monovalent cations can be easily separated from monovalent cations and from other bivalent cations like calcium. Aldex CR 2012 is used for decalcification of brine solutions in cholralkali industry. Other applications of this resin are removal of bivalent metal cations from process industry using metals, electroplating and pickling baths, hydrometallurgy, battery plants for lead removal, electrionic industry etc.
