Description:

"The Bureau of Mines investigated methods for selectively eluting mercury, silver, and gold from strong-base anion-exchange resins, including rohm and haas resins ira-430 and 900, and dow chemical resins 21k, sma-1, and sbr. Resins were typically loaded to 145 oz/st of each metal. Loaded resins were eluted with h2so4, nacl- hcl, naocl, and naclo4 solutions. The resins tested had similar elution characteristics for mercury and precious metals. The best selective elution scheme was achieved by eluting in a column with 2n h2so4 to recover 99 to 100 pct hg, with 200 g/l nacl in 1n hcl to recover 99 to 100 pct ag, and with 2m naclo4 to recover 79 to 89 pct au." - NIOSHTIC-2
