Product Description

Chelating Macroporous Styrene Series
  Weak Base Bis-picolylamine Groups Anion Exchange Resin
     for Copper, Nickel, Cobalt Adsorption/Removal

PRODUCT DATA SHEET:

D720 is a macroporous styrene-based weak-base anion exchange resin with coordinating amine groups. With its active chelating bispicolylamine functional groups, this resin model performs well in removing heavy metal ions in acidic solutions. Specifically, its advantage of highly firm structure and excellent chemical stability, large mesh size & chelating exchange capacity as well as its fast adsorption velocity and high adsorption capacity qualify D720 quite well to adsorb or remove Copper, Nickel and Ferric ions in Cobalt electrolyte, particularly active for selective adsorption of Copper within strong-acid solutions(PH<2).
Moreover, compared with congeneric weak-base resin products, D720 receives high credits for its high elution rate of regeneration, high mechanical &crushing resistance strength, and foremost fine permeation resistance, which ensures full integrity of resin particles in operation, low operating costs, low broken rate of beads in long-term use and so as to minimize the annual replenishment rate of resin.
