ASTM E248 covers the procedure to determine the manganese in manganese ores by pyrophosphate complexed permanganate potentiometric titrimetry. This method can be applied to manganese ores containing manganese in the range of 15% to 60%. This definitive test method is intended to be used as a referee method for compliance with compositional specifications for manganese content.
ASTM E248 Determination of Manganese in Manganese Ores by Pyrophosphate Complexed Permanganate Potentiometric Titrimetry
What is ASTM E248?
ASTM E248 Sample Preparation Guide
A sample weighing 0.30 to 0.40 g is taken for the ASTM E248 test (Standard Test Method for Determination of Manganese in Manganese Ores by Pyrophosphate Complexed Permanganate Potentiometric Titrimetry).
What are the Testing Procedure and Requirements of ASTM E248?
The test sample used in ASTM E248 is decomposed by treatment with HCl, HNO3, HF, and HClO4. Sodium phosphate is added to adjust acidity. The manganese content is determined by oxidation of trivalent manganese by using a standard solution of potassium permanganate. A potentiometric titration apparatus is used for determining the end point. The end point is determined potentiometrically.
Analysis Result and Interpretation:
- ASTM E248 covers the procedure to determine the manganese in manganese ores by pyrophosphate complexed permanganate potentiometric titrimetry.
- For ASTM E248, the percentage of manganese is calculated as follows,
Where,
A = KMnO4 solution required for titration of the
sample, mL
B = normality of the KMnO4 solution, and
C = sample used, g.
