D201 Macroporous Strong Base Anion Exchange Resin for Gold Recovery
Macroporous Type strongly basic styrene type anion exchange resin for pure water preparation, wastewater treatment, desalination treatment, adsorption of gold in cyanide pulp, extraction of tungsten and molybdenum in biochemical products and hydrometallurgy.
Features:
Appearance: Milky white or light gray opaque spherical particles.
Ionic form:Cl-
Volume complete exchange capacity(mmol/ml):≥1.2
Product Details:
D201 series anion exchange resin is a quaternary ammonium group[-N(CH3)3OH]-containing macroporous styrene diethylene styrene cross-linked networked copolymer spherical particles. The structure of D201 exchange resin is similar to 201×7, but the exchange rate, penetration strength and anti-pollution ability are higher. D201 series resins are equivalent to Purolite A500; Amberlite IRA900; LeVatti M500; Dow Dowex MSA-1.
