Abstract
P is precipitated as magnesium ammonium phosphate hexahydrate in the presence of the Mg complex of di-K-ethylenediaminetetracetate, which exchanges the interfering Ca++ for Mg++. The excess Mg++. is washed out with NH4OH after centrifugation of the precipitate. Mg of the precipitate is titrated with di-K-ethylenediaminetetra-acetate using Eriochrom black T. as indicator. The results agree with the gravimetric methods and that of Bell-Doisy.Keywords
