|Title:||Determination Of Iron In Iron Ores Using Enthalpimetric Flow Injection Analysis|
De Oliveira W.A.
|Abstract:||A method is described in which a dissolved sample of iron ore is injected into a flow manifold, after passing through a silver reductor column. The sample then merges with a dichromate solution and generates an enthalpimetric signal due to the oxidation of iron(II). The precision of the proposed method is approximately 0.3% and the sampling rate is 85 samples per hour. Interference from vanadium was negligible and titanium did not interfere. The results of the analysis of samples of iron ores by the proposed method agree with those obtained by titrimetric analysis.|
