Direct Method of Iodometric Determination of Ferric Iron in Slags

Takuho Ikegami and Shôji Morita


Abstract:

A direct method of iodometric determination of ferric iron in slags has been studied. Under the conditions of the procedure recommended, especially by the addition of about 5 g of KI, the necessity for warming the solution after the first end point and then retitrating had been eliminated, and best results were obtained rapidly in about 10 minutes. Our procedure will offer far more simple and rapid direct method of estimating the content of ferric iron in slags than the usual method in which each content of the total iron and the ferrous iron are respectively determined and from the difference between these two contents the content of the ferric iron is determined.
