Title	SOLUTION TECHNIQUE FOR ANALYSIS OF SILICATES
Accession No	00228843
Authors	Suhr, N H; Ingamells, C O
Journal Title	Analytical Chemistry
Corp. Authors / Publisher	American Chemical Society
Abstract	A NEW SOLUTION TECHNIQUE MAKES POSSIBLE THE RAPID AND PRECISE DETERMINATION OF MOST MAJOR AND MINOR CONSTITUENTS OF SILICATES IN A SINGLE SAMPLE. SOLUTION IS EFFECTED BY ADDING THE MELT OF SAMPLE FUSED WITH LITHIUM METABORATE DIRECTLY TO COLD DILUTE NITRIC ACID THAT CONTAINS THE INTERNAL STANDARD COBALT. THE SOLUTION IS ANALYZED WITH AN EMISSION SPECTROMETER USING A ROTATING DISK TECHNIQUE. DATA FOR PRECISION ARE GIVEN FOR THE OXIDES OF SI, AL, MG, CA, SR, BA, TI, MN, FE, CR, CU, ZN, ZR, AND NI. ACCURACY OF THE METHOD IS EVALUATED BY COMPARISON WITH CHEMICAL ANALYSES OF FOUR ROCK SAMPLES. NA AND K ARE DETERMINED ON THE SAME SAMPLE SOLUTION BY FLAME PHOTOMETRY. THE SAME SOLUTION CAN ALSO BE USED TO DETERMINE VARIOUS ELEMENTS COLORIMETRICALLY, SPECTROGRAPHICALLY, AND BY X-RAY FLUORESCENCE SPECTROMETRY. /AUTHOR/
