Heretofore the analysis of the iron oxide contained in sponge iron has been conducted in general by the "mercuric chloride method", which consists in first dissolving the metallic iron in the mercuric chloride solution, then eliminating the metallic mercury in the residue with alcoholic solution of iodine or chlorine gas and finally determining the residual iron oxide. The present method tried by the author is that of dissolving the metallic iron in the aqueous iodine solution instead of mercuric chloride solution, determining the iron oxide in the residue, and comparing the result with that obtained by the abovementioned method. The result agreed satisfactorily with the mercuric chloride method, which had been recognized to be the most accurate, and showed that the iron oxide may be determined simply and precisely by the present method.
