Description
Так как растворение железа проходит строго стехиометрически с образованием РеСЬ, то металлическое железо определ ют как 1/3 двухвалентного железа, образующего нри растворении.Since the dissolution of iron proceeds strictly stoichiometrically with the formation of FES, metallic iron is defined as 1/3 of divalent iron forming at dissolution.

Предмет изобретени Subject invention
Способ выделени металлического железа из восстановленных материалов, преимущественно дл его аналитического определени , путем селективного растворени раствором хлорного железа в присутствии добавок, о тличающийс тем, что, с целью повышени селективности и ускорени процесса, в качестве добавок используют хлористые соли щелочных металлов, например натри , кали .A method for separating metallic iron from reduced materials, mainly for its analytical determination, by selectively dissolving ferric chloride solution in the presence of additives, in order to increase the selectivity and speed up the process, alkali metal chloride salts, for example, Kali.
