| 520 | 3 |a“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. |
