ALDEX Chelation Resin (CR) Series
CR 80 Chelation Resin Series
Aldex CR 80 is a specially developed chelating resin for selective removal of mercury and noble metals from industrial effluents. Aldex CR 80 is a macroporous resin having a poly-isothiouronium group, which is highly selective for mercury. It is also selective to other noble metals like gold, platinum and metals of the platinum group. Sodium, alkaline earth and heavy metals such as iron, copper, and lead do not interfere in the selective removal of mercury and noble metals.
