| Название (рус.): | Стекло и стеклянная посуда. Анализ экстрагирующих растворов. Часть 5. Определение содержания оксида железа (III) методами молекулярной абсорбционной спектрометрии и пламенной атомной абсорбционной спектрометрии |
| Название (англ.): | Glas and glassware; analysis of extract solutions; part 5: determination of iron(III) oxide by molecular absorption spectrometry and flame atomic absorption spectrometry |
| Описание (англ.): | The principle of the method specified is reducing the iron in the extract solution, complexing, extracting the complex into chloroform and measurement of the optical density of the resulting colour complex by means of a molecular absorption spectrometer at 533 nm or evaporating with hydrofluoric and perchloric acids, dissolving of theresidue in hydrochloric acid, measuring the absorption using a flame atomic absorption spectrometer at 248,3 nm. Measures the concentration of iron, expressed as its oxide Fe |
