GB/T 24583.1-2009 Determination of vanadium content in vanadium-nitrogen alloys using ferrous sulfate ammonium Titrimetric method. Applicable to all kinds of vanadium-nitrogen alloy products. Sample Handling of vanadium-nitrogen alloys converts vanadium into a titratable state, using the oxidation and reduction reaction of ferrous sulfate ammonium and vanadium, indicating the end point with an appropriate indicator, and calculating the vanadium content by the amount of ferrous sulfate ammonium standard solution. Standard specifies the requirements of Burette and other instruments, specifies the preparation of reagents. Detailed description of Sample Handling steps, including sample dissolving and elimination of interfering elements. Standardized titration operation process. According to this standard, vanadium content can be accurately determined, providing key data for mass evaluation of vanadium-nitrogen alloys and control of raw materials for iron and steel smelting.
