Determination of silicon by measurement of the absorbance of the n-amyl alcohol extract of α-silicomolybdic acid (application to high-purity copper and brasses): M34-20/77E-PDF

“A procedure involving n-amyl alcohol extraction of α-silicomolybdic acid and spectrophotometric measurement of the extract (at 350 mμ) has been applied to the determination of trace amounts of silicon in high-purity copper metal and brasses. Interference from phosphorus and arsenic is eliminated by the selective destruction of their heteropoly complexes in a 3N sulphuric acid medium prior to the extraction of the silicon complex"--Abstract, p. i.
