GB/T 4698.12-1996 is used for the determination of vanadium content in sponge titanium, titanium and titanium alloys, using the ferrous sulfate ammonium Titrimetric method. It is suitable for samples of this type of metal materials. The principle is to use ferrous sulfate ammonium and vanadium to undergo oxidation reduction reaction to determine the amount of vanadium. The standard specifies the required instruments, such as Burette, etc., and specifies the preparation and use of reagents. Detailed description of Sample Handling steps, including dissolve, separation of interfering elements, etc., as well as titration operation procedures, such as the addition speed of titrants, and the method of judging the end point. According to this standard, the vanadium content can be accurately determined, providing key data for the quality control and performance evaluation of sponge titanium, titanium and titanium alloys
