Determination of magnesium by the Titan yellow and ammonium phosphate methods.

The determination of serum magnesium by the molybdivanadate method for phosphate.

During the past decade there has been an increasing interest shown in the study of electrolyte balance. Magnesium, however, has played a minor r81e in these studies. There are perhaps two reasons for this; first, that serum magnesium levels remain fairly constant and, second, that magnesium determinations require special technique and equipment and are time-consuming procedures as well. There h...

Investigation of the effect of phosphate agent type on setting time, flowability, hydration and dehydration of magnesium phosphate cement.

Magnesium phosphate cements (MPC) are the most developed kind of chemically bonded ceramics which form through the reaction of magnesium oxide and soluble phosphate salts. Therefore, study of different magnesium phosphate cement systems is considered important according to the type of phosphate agent used. In this study, effect of mono-ammonium phosphate (MAP), di-ammonium phosphate (DAP), and ...

Spectrophotometric Determination of Magnesium in Blood Serum Using Magon.

PRESENT METHODS for the determination of magnesium in biologic fluids and their inadequacies have been reviewed by Maclntyre and Wootton (1). In 1957, Mann and Yoe (2) introduced a color reagent for magnesium called Magon, 1-azo-2-hydroxy-3-(2,4-dimethylcarboxanilido )naphthalene-1’(2-hydroxybenzene), which they reported has a sensitivity 8 times greater than that of Titan yellow. Since then, M...

A flame photometric method for the determination of plasma magnesium after hydroxyquinoline precipitation.

The numerous methods for determining magnesium in biological fluids that have been reported in the past have varied from chemical to spectrochemical techniques. Among these various procedures have been included gravimetric, calorimetric, and titrimetric techniques. The gravimetric micromethod based on the precipitation of magnesium B-hydroxyquinoline in hot ammoniacal solution, first utilized b...
