GOST R 54499-2011

ГОСТ Р 54499-2011

Drinking water. Luminescent method for determination of uranium content

Вода питьевая. Люминесцентный метод определения содержания урана

Status: Effective - Introduced for the first time. IUS 11-2012

This standard applies to drinking water and water from surface and underground drinking water supply sources and establishes a method for determining the mass concentration of uranium using luminescence in the wavelength range from 500 to 550 nm in the presence of sodium polysilicate excited by light in the wavelength range from 250 to 350 nm: - for the range of measurements of the mass concentration of uranium from 0.002 to 1.000 mg / dm3 using the calibration characteristic - the dependence of the luminescence intensity on the mass concentration of uranium (option A); - for the range of measurements of the mass concentration of uranium from 0.0006 to 1.0000 mg / dm3 by adding an additive of uranium to the sample of the analyzed water (variant B). Option B is also recommended to use in the presence of the influence of interfering factors. Option B is arbitration. If the uranium content exceeds the upper limit of the range, the sample may be diluted with distilled water, but not more than 100 times

Настоящий стандарт распространяется на питьевую воду и воду поверхностных и подземных источников питьевого водоснабжения и устанавливает метод определения массовой концентрации урана с использованием люминесценции в области длин волн от 500 до 550 нм в присутствии полисиликата натрия, возбуждаемой светом в области длин волн от 250 до 350 нм: - для диапазона измерений массовой концентрации урана от 0,002 до 1,000 мг/дм3 с использованием градуировочной характеристики - зависимости интенсивности люминесценции от массовой концентрации урана (вариант А); - для диапазона измерений массовой концентрации урана от 0,0006 до 1,0000 мг/дм3 путем внесения добавки урана в пробу анализируемой воды (вариант Б). Вариант Б рекомендуется также использовать при наличии влияния мешающих факторов. Вариант Б является арбитражным. Если содержание урана превышает верхнюю границу диапазона, то допускается разбавление пробы дистиллированной водой, но не более чем в 100 раз
