THE SUCCESSIVE DETERMINATION OF MANGANESE, SODIUM AND POTASSIUM OXIDE IN CEMENT BY FLAME PHOTOMETRY

IT HAS BEEN SHOWN THAT MANGANESE IN CEMENT CAN BE DETERMINED FLAME-PHOTOMETRICALLY USING THE BECKMAN MODEL DU SPECTROPHOTOMETER WITH SPECIAL ATTACHMENTS AND PREPARING CALIBRATION CURVES WITH STANDARD SOLUTIONS. BY INCLUSION OF KNOWN AMOUNTS OF SODIUM AND POTASSIUM IN THE STANDARD SOLUTIONS, THE SAME SOLUTIONS MAY BE USED ALSO TO OBTAIN DATA FOR CALIBRATION CURVES FOR THE DETERMINATION OF THESE LATTER ELEMENTS. THE ANALYSES FOR SODIUM AND POTASSIUM MAY BE MADE ON THE CEMENT SOLUTIONS PREPARED FOR THE DETERMINATION OF MANGANESE USING EITHER THE BECKMAN DU OR THE PERKIN-ELMER MODEL 146 FLAME PHOTOMETER. IT WAS FOUND UNNECESSARY TO SEPARATE ANYTHING FROM THE SOLUTIONS OF CEMENT SAMPLES ESCEPT THE SMALL AMOUNT OF HYDROCHLORIC ACID-INSOLUBLE MATERIAL THAT HAD TO BE REMOVED BY FILTRATION TO OBTAIN CLEAR SOLUTIONS. /PCA/
