Testing Methods for Vanadium Content in Ferrovanadium​

Common Testing Methods

Typical Procedure for ICP‑OES (Industry Favorite)

1. 1.
   Sample preparation: Weigh ~0.1 g FeV, digest in acid (HCl/HNO₃/HF if needed).
2. 2.
   Dilution: Make up to known volume with deionized water.
3. 3.
   Calibration: Use certified V standards.
4. 4.
   Analysis: Run sample, record V emission intensity, calculate concentration.
5. 5.
   Reporting: Express as %V in alloy.

Quality Assurance

• •
  Run blank​ and reference materials​ with each batch of samples.
• •
  Check instrument calibration daily/weekly.
• •
  Use duplicate analyses​ to confirm precision (RSD < 1–2 %).
