title: Polarography of the alkaline-earth metals--II: The adsorption wave for the Magnesium-Eriochrome Black T complex.
abstract: Magnesium-Eriochrome Black T in ethylenediamine medium gives a polarographic adsorptive wave at -0.7 V (vs. an Ag/Hg electrode). It gives a limit of detection for magnesium of 2 x 10(-8)M. It is made the basis of a method for determination of magnesium in serum, water and various salts, without any pretreatment. The method is very rapid, sensitive and convenient for serum analysis.
