概要
- 論文の詳細を見る
It is difficult to find satisfactory organic solvents for the extraction of reduced molybdosilicic acid, but extraction is possible with isoamyl or isobutyl alcohol if the acid concentration of the aqueous solution is increased before the extraction, the best results being obtained by extraction with isoamyl alcohol from 3.5-4.5N sulphuric acid medium. This makes the reduced molybdosilicic acid method much more sensitive and permits the determination of microgram amounts of silicon in various kinds of high-purity metals
