Thiourea Chelating Resin for precious metal extraction in waste water treatment equal to purolite MTS9200

GD200 Thiourea Chelating Resin for Precious Metal Extraction Resin Same as Purolite S920 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.
Features:
Appearance: Milky to light yellow opacity spherical beads
Ionic form:H+
Volume complete exchange capacity(mmol/ml):≥1.2
Product Details:
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.
Advantage:
1) Special chiral functional groups 
2) Good selectivity
3) Excellent mechanical strength
4) Large exchange capacity.
5) High physical strength.

Phsical and chemical property:
