Качество воды. Определение содержания селена. Спектрометрический метод атомной абсорбции с применением гидридов
Название (англ.):
Water quality; determination of selenium; atomic absorption spectrometric method (hydride technique)
Описание (англ.):
Under the conditions of the method specified (thermal decomposition of selenium hydride for AAS), only Se(IV) is quantitatively converted to the hydride. To avoid errors in determination, other oxidation states need to be converted to Se(IV) prior to the determination. The absorbance is measured at a wavelength of 196,0 nm. The method determines selenium andorganically bonded selenium in drinking waters, ground waters and surface waters, in a concentration range of 1
