Chelating Resin Macromolecular Polymer  

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. 1) Special chiral functional groups 2) Good selectivity 3) Excellent mechanical strength 4) Large exchange capacity. 5) High physical strength.   1. Physical and chemical property Index name GD200 Appearance Milky white to beige opaque spheres Ion form H type Functional group -S-C(NH)NH2 Volume exchange capacity  mmol/ml（H type） ≥ 1.2 Saturated adsorptio…
