Determination of Relationship between Autoignition of Sponge Iron and Specification of the Iron Ores
Sponge iron (DRI) due to the high surface area, often shows a high tendency to re-oxidation and at some cases spontaneous combustion (autoignition). In this work, re-oxidation behavior and autoignition of sponge iron, produced from different types of iron ore has been investigated. Isothermal and non-isothermal re-oxidation experiments were carried out on each type of DRI and their autoignition...

متن کاملSerum iron determination.
N IRON REAGENT, 4 ,7-diphenyl-1 , lO-phenanthroline, which has a more desirable sensitivity than other known iron reagents, has been introduced by Case (1), has been used by Smith et at. (2) in the estimation of iron in water, and in serum by Peterson (3) who reported the molar absorbency index of the iron complex of this new reagent as almost three times that of a-a’-dipyridyl or o-phenanthrol...
متن کاملSerum iron determination.
A simple, rapid, and sensitive method for the determination of iron in serum or plasma is described. The procedure is carried out at room temperature with 2 ml. of serum or plasma, or with 1 ml. if high values are expected; it can be applied to turbid or jaundiced samples, whether previously frozen or not. An ethanolic solution of 4: 7-diphenyl-1: 10-phenanthroline is used to produce a coloured...
متن کاملDetermination of iron in solutions containing iron complexes.
A method of estimating the iron content of solutions containing haemoglobin, ferritin, or ferrioxamine is described. Iron is released by treatment with acid permanganate and ascorbic acid before conventional determination by an Auto Analyzer technique.
