D840 (H form) resin is a premium grade, macroporous chelating exchange resin with thiouronium functional groups. It is designed to chelate/remove many heavy metal cations, including free state mercury and noble metals, such as silver, gold, platinum and palladium. Its high selectivity allows it to remove mercury down to extremely low ppb levels.
D840 (H form) resin has even particle size and good mechanical strength. High concentrations of sulfates and chlorides normally do not
affect its selectivity to heavy metals, but the presence of chelating or complexing agents may affect the operating capacity.
