Abstract
Изобретение относитс к области физико-химического анализа солевых систем и может быть использовано при определении концентрации нитритов в расплавленных нитратах щелочных металлов . Целью изобретени вл етс увеличение экспрёссности анализа нитратных расплавов щелочных металлов на содержание нитрит-ионов. В качестве индикаторного электрода используют металл, пассивирующийс (устойчивый ) в нитратных расплавах, например никель, молибден; непосредственно перед измерени ми очищают его, измерени начинают с момента погружени его в расплав, фиксируют максимальные значени потенциала и по. калибровочной кривой определ ют кон центрацию нитритов щелочных металлов. 3 ил. СОThe invention relates to the field of physico-chemical analysis of salt systems and can be used in determining the concentration of nitrites in molten alkali metal nitrates. The aim of the invention is to increase the efficiency of the analysis of nitrate melts of alkali metals on the content of nitrite ions. As an indicator electrode, a passivated (stable) metal in nitrate melts is used, for example nickel, molybdenum; immediately before the measurements, they clean it, the measurements begin from the moment it is immersed in the melt, the maximum values of the potential and are recorded. the alkali metal nitrite concentration is determined by a calibration curve. 3 il.
