Bismuth can be separated by ion-exchange adsorption on Dowex 21 K resin from ca. 0.25 M HCl, after removal of volatile interferences by distillation in acid-oxidizing medium. Bismuth is eluted from the column with 1 M sulfuric acid. The method is useful in the absorptiometric determination of bismuth with thorin, as well as in other photometric methods. © 1963.
