Adsorption properties and mechanism of gold were studied under different conditions. The results showed that dibutyl carbitol (DBC) levextrel resin is a new selective stationary phase for gold. It was found that gold can be retained on DBC resin column in mol/L HCl. The eluant of gold is 2% thiorea solution.
