A SHORT METHOD FOR THE FLAME PHOTOMETRIC DETERMINATION OF MAGNESIUM, MANGANIC, SODIUM, AND POTASSIUM OXIDES IN PORTLAND CEMENT

A FLAME PHOTOMETRIC COMBINATION METHOD HAS BEEN DEVELOPED WHEREBY ONE SET OF STANDARD CALIBRATING SOLUTIONS AND ONE SOLUTION OF CEMENT ARE ALL THAT ARE REQUIRED FOR THE SUCCESSIVE ANALYSIS OF THE LATTER FOR MAGNESIUM, MANGANIC, SODIUM, AND POTASSIUM OXIDES. THE ACCURACY OF THE METHOD IS EXCELLENT FOR MANGANIC OXIDE, AND GOOD FOR MAGNESIUM, SODIUM, AND POTASSIUM OXIDES. THE PRECISION IS VERY GOOD FOR ALL FOUR OXIDES. USE OF THE PROCEDURE LEADS TO MORE RAPID AND CONVENIENT ANALYSES. THE METHOD IS RECOMMENDED AS A RAPID CONTROL PROCEDURE WHEN ALL FOUR OXIDES MUST BE DETERMINED. THE ASTM FLAME PHOTOMETRIC METHOD IS SIMPLER WHEN ALKALI VALUES ONLY ARE REQUIRED. HOWEVER, SOME EVIDENCE INDICATES THAT THE POTASSIUM OXIDE RESULTS WERE MORE ACCURATE WHEN SILICA AND THE AMMONIUM HYDROXIDE GROUPS WERE REMOVED. /PCA/
