DIAION™ CR20 is a polyamine type chelating resin. It has a high selectivity for divalent metal ions, especially transition metal elements, than monovalents. It is recommended for chemical process separations, and metals removal and recovery from waste water.
DIAION™ CR11 is an iminodiacetate type chelating resin. It has a high selectivity for multivalent metal ions, especially transition metal elements like Fe(III) and Cu(II), than monovalents. It also provides rapid kinetics, high operating capacity, low swelling and shrinking ratio, and excellent mechanical stability. It is recommended for chemical process separations, and metals removal and … Read more
