Abstract
IN a communication in Nature, Mr. H. Wolfson1 reported that iron can be determined satisfactorily on the polarograph if the solution contains triethanolamine. This method seemed promising for the measurement of iron in small quantities, which has hitherto been practically impossible. It would be particularly suitable for use on biological materials and foodstuffs, especially if lead and copper could be measured in the same solution. In Mr. Wolfson's solutions, containing ammonia, copper gives two steps, the second one interfering with that of ferric iron. He stated, however, that the properties of the solution can be considerably modified by the presence of a strong alkali. When this suggestion was followed up, it was found that the steps for copper, lead and iron can be separated and that the three metals can be determined simultaneously under suitable conditions.
