Are there any factors that affect the detection of vanadium in wastewater?

Thread Content

Dear experts, I would like to determine the vanadium content in wastewater. Are there any things I need to keep in mind when conducting these tests? Are there any interfering factors when testing for vanadium? Thank you!

Factors such as the reduction reaction time, the pH value during the neutralization and precipitation process, and coagulants all have an impact on the vanadium residue in wastewater

In the final step of the vanadium(IV) to vanadium(V) transformation, a few drops of NaNO2 must be added to ensure that all manganese ions in different oxidation states are reduced to the divalent state.
