- Scope
- This part specifies the principle, reagents and materials, instruments, sampling and preparation, analysis steps, calculation of results, etc. for the determination of manganese content by potentiometric titration and ammonium ferrous sulfate titration. This part is applicable to the determination of manganese content in manganese ore and manganese concentrate. Method 2 is not applicable to the determination of manganese content in manganese ore and manganese concentrate with vanadium content (mass fraction) greater than 0.05%. Measurement range (mass fraction): Method 1 The potentiometric titration method is ≥ 15.00%, and the ferrous ammonium sulfate titration method is 8.00% to 60.00%.
