ESTIMATION OF IRON (Fe) BY WET CHEMICAL

At first, the iron ores were digested using concentrated HCl and the iron content was determined by titrating against standard potassium dichromate following the usual method. On the other hand, the vanadium content of the same set of iron ores were determined using ICP-OES and the vanadium was removed using the following method prior to titration against standard potassium dichromate.

Pollution-free method for the determination of iron in

1982-8-1  No instrumental method has been found accurate enough for the determination of iron in iron ores, although many routine iron determinations are carried out by XRF. Two titrimetric methods have been recommended by ASTM and ISO for the determination of total iron in iron ores and concentrates. 1-3 They differ only in minor details.

2020-4-30  Abstract: Determination of Iron in Natural samples was carried out using the Spectrophotometric methods. For each Natural Samples (determined in duplicate) ash solution was prepared and its aliquot for analysis by Spectrophotometric methods has been done. Mean value for duplicate analysis of each sample determined by the method was tabulated according to Natural sample. The describe method is very simple, rapid, sensitive and selective for estimation of Iron. Result of the study suggests theta method can be used satisfactory for the analysis of iron.
