Стекло и стеклянная посуда. Анализ экстрагирующих растворов. Часть 2. Определение содержания оксида натрия и оксида калия методами пламенной спектрометрии
Название (англ.):
Glass and glassware; analysis of extract solutions; part 2: determination of sodium oxide and potassium oxide by flame spectrometric methods
Описание (англ.):
The principle of the method specified is spraying the extract solution into the flame of the burner of an emission or absorption spectrometer, if necessary with the addition of a spectrochemical buffer solution, or into the flame of a filter flame spectrometer without thisaddition. For FES and FAAS, the lines at 589,0 nm and 766,5 nm, respectively, are used and compared with the measurements of reference solutions, for a flame filter spectrometer, the specific filters are used. Measures the concentrations of sodium and potassium, expressed as their oxides Na
