Scope

This Part specifies the principle, reagents and materials, instruments, sampling and
sample preparation, analytical procedures, result calculation, etc. of using potassium
dichromate titrimetric method and 1,10-phenanthroline spectrophotometric method to
determine the total iron content.
This Part is applicable to the determination of total iron in the manganese ores and the
manganese concentrates with vanadium content (mass fraction) < 0.02%; the test
range (mass fraction): Method-I potassium dichromate titrimetric method is
2.00%~25.00%; while Method-II 1,10-phenanthroline spectrophotometric method is
0.10%~3.00%.
