1. Description
Hydrolite ZGD840 resin is a chelating resin containing a weakly acidic thioureide group (-CH2 – SC-NHNH2 ) in a styrene-diethenic benzene copolymer with a macroporous structure. This product is capable of fixing and chelating one or more cations over a wide range, even in solutions with high concentrations. Its primary application is the separation and purification of free mercury and precious metals. It is characterized by a uniform grain size and high mechanical strength.
