• Hummel-Dreyer's method was examined for its applicability to inorganic complexes, and a modified method was proposed. A sample solution containing magnesium and diphosphate was eluted with magnesium chloride solution on a gel column. The change of magnesium concentration in an effluent was measured with an atomic absorption detector. From the peak area of the eluted complex the stability constants (1g β<SUB>1</SUB>) at <I>I</I>=0.1 and 25 °C were evaluated to be 5.57 in tetramethylammonium chloride solution and 5.06 in sodium perchlorate solution. In the modified method the total magnesium concentration in a sample solution is made to be much higher than that in an eluent. This enables one to shorten the elution time.
