抄録

The Spectrophotometric method for quantitatively determining minute amounts of Be is based on the reaction of Be with aluminon in the presence of a sequestering agent which acts to remove interferences (Al, V, etc.). A red-colored complex is formed having an absorption peak at 530 mμ. The system obeys Beer’s law between the limits of 0.01 and 0.1 mg of Be. The method is accurate and precise. A satisfactory procedure for determing Be in stainless steels was developed. The interfering effect caused by large amounts of Fe, Ni, Cr, etc. were eliminated by the magnetic mercury cathode method.
