Water. Method for determination of total mercury by flameless atomic absorption spectrometry
Вода. Методы определения содержания общей ртути беспламенной атомно-абсорбционной спектрометрией
Status: Effective - Introduced for the first time. IUS 4-2013
This standard applies to drinking, natural (surface and underground) and wastewater and establishes a flameless atomic absorption method for determining the mass concentration of total mercury (cold vapor method) after oxidizing all present forms of mercury to a bivalent state during mineralization of the water sample being analyzed, recovery mercury (II) to metal, measuring the absorption of resonant radiation by atomic mercury vapor at a wavelength of 253.7 nm and the subsequent calculation of the mass concentration of total mercury. The standard establishes three methods for determining the total mercury content: 1 - determination of the total mercury content after mineralization with potassium dichromate. The method is used to analyze drinking and natural waters used in drinking water supply, with concentrations of total mercury from 0.1 to 5.0 μg
Настоящий стандарт распространяется на питьевые, природные (поверхностные и подземные) и сточные воды и устанавливает беспламенный атомно-абсорбционный метод определения массовой концентрации общей ртути (метод «холодного пара») после окисления всех присутствующих форм ртути до двухвалентного состояния при минерализации анализируемой пробы воды, восстановления ртути (II) до металлической, измерении поглощения резонансного излучения атомным паром ртути при длине волны 253,7 нм и последующем расчете массовой концентрации общей ртути. Стандарт устанавливает три метода определения содержания общей ртути: 1 - определение содержания общей ртути после минерализации двухромовокислым калием. Метод применяют для анализа питьевых и природных вод, используемых в хозяйственно-питьевом водоснабжении, при концентрациях общей ртути от 0,1 до 5,0 мкг/дм куб.; 2 - определение содержания общей ртути после минерализации марганцовокислым калием и надсернокислым калием. Метод применяют для анализа природных, промышленных сточных вод и вод, предназначенных для хозяйственно-питьевых нужд, при концентрациях общей ртути более 0,2 мкг/дм куб.; 3 - определение содержания общей ртути после минерализации ультрафиолетовым облучением. Метод применяют для анализа питьевых вод и вод, предназначенных для производства напитков в пищевой промышленности. Метод позволяет определять массовую концентрацию общей ртути более 0,1 мкг/дм куб
