Gold(III) is selectively sorbed from 1M hydrochloric acid by a short column containing a special acrylate resin. Then the gold is eluted from the column with acetone-hydrochloric acid, and the absorbance of the effluent is measured at 340 nm. Gold(III) may be successfully separated and determined in samples containing many other metal ions.
