Abstract
PURPOSE:To accurately measure at the time of measuring the content of plural metal ions by absorption photometry utilizing absorption spectrum, by removing overlapping of a part or whole overlapped absorption spectrum by additives. CONSTITUTION:Content of each metal ion in mixed solution containing at least two kinds or more of metal ions of copper ion, iron ion, rare earth metal ion etc., is measured by absorption photometry utilizing absorption spectrum of each metal ion. On occasion of overlapping a part or whole absorption spectrum of two kinds or more of metal ions, additives such as organic reagent (e.g. alizarin, xylenol orange etc.), oxidizing agent (e.g. trivalent iron ion solution etc.), reducing agent (e.g. zinc powder, zinc amalgam etc.) are added and measurement is carried out by giving variation to the absorption spectrum by acting said additives on the metal ions to be measured or another metal ions to remove overlapping of the absorption spectrum.
