چکیده
This report presents a method for the quantitative determination of magnesium and calcium in a single specimen of urine, stool, and food by formation and calorimetric determination of their respective phosphates. The method makes use of some of the principles advanced by Roe and Kahn (1) for determination of serum calcium, and by Denis (2) for serum magnesium. Phosphorus determinations are performed by the method of Fiske and Subbarow (3).

Determination of calcium and magnesium in serum, urine, diet, and stool by atomic absorption spectrophotometry.
ATOMIC ABSORPTION was developed by Walsh and his associates (1) as an analytical technic applicable to the determination of many metals. Willis (2-4) found that this technic was applicable in particular to tile determination of calcium and magnesium in Serum and urine. These published results indicated that atomic absorption spectrophotometry would be a simple, rapid, and practical method for t...
متن کاملDetermination of calcium in urine by the chloranilate method.
Evidence is presented that the colorimetric chloranilate calcium method can be accurately applied to urine provided that elimination of interfering substances, which include magnesium, is performed prior to the determination. Isolation of calcium as the oxalate, followed by perchioric acid digestion, has been shown to be an acceptable method whereby urinary calcium can be put in a suitable stat...
