| Abstract: | An improved method is described for the voltammetric determination of Pb, Cd and Cu in calcium fluoride. A shortening of the time required has been achieved by omitting the removal of the fluoride ions and by measuring blank and sample signals in one and the same solution (before and after adding CaF2). The results were in satisfactory agreement with those obtained by other methods. |
