GD200 Thiourea Chelating Resin for Precious Metal Extraction Resin
Thiourea Chelating Resin is widely usded in the water treatment industry applied to the adsorption and extract of precious metal ions, such as Au, Pt, Pd, etc. with obvious effect and high regeneration ability.
Introduction
GD200 chelating resin is a macromolecular polymer with special chiral functional groups on the macroporous styrene-divinylbenzene skeleton.
GD200 has a thiourea functional group, which can selectively remove mercury and recover precious metals in industrial wastewater.
GD200 is more resistant to oxidation than other sulfur-based resins and is not afraid of contact with air, but free chlorine and strong oxidants will destroy it, which must be removed by activated carbon filtration first.
Advantages:
Special chiral functional groups
Good selectivity
Excellent mechanical strength
Large exchange capacity
High physical strength
