| Abstract: | A simple method for the potentiometnc determination of thallium is described. Thus is based essentially on the precipitation of thallic hydroxide by alkaline ferricyanide and the back titration of excess K3[FeCN)6] by standard sodium arsemte according to Kolthoff's method Under thc specified experimental conditions. the reduction of trivalent thallium is not effected by As2O3 and the procedure offers therefore a unique advantage of simplicity and accuracy. |
