| Название (рус.): | Качество воды. Определение содержания натрия и калия. Часть 3. Определение содержания натрия и калия спектрометрическим методом эмиссии в пламени |
| Название (англ.): | Water quality; determination of sodium and potassium; part 3: determination of sodium and potassium by flame emission spectrometry |
| Описание (англ.): | The principle of the method specified is aspirating the sample into a gas flame of sufficient thermal energy to cause any sodium and potassium present to emit its characteristic radiation and measuring the intensity at a wavelength of 589,0 nm for sodium and 766,5 nm for potassium. Applies to water samples with a mass concentration of sodium and potassium of upto 10 mg/l. For higher concentrations, a smaller test portion is taken for analysis. The lower limits of determination are less than 0,1 mg/l for both sodium and potassium. |
