GB/T 24583.3-2009 Determination of nitrogen content in vanadium-nitrogen alloys by distillation-neutralized Titrimetric method. This standard is applicable to all kinds of vanadium-nitrogen alloy products. The vanadium-nitrogen alloy samples are first processed to convert the nitrogen element into ammonia and distillation out, then the ammonia distillation is absorbed with sulfuric acid standard solution, and finally the sodiumhydrate standard solution is used for back titration. The standard specifies the requirements of distillingapparatus, Burette and other instruments, and specifies the preparation of reagents. Detailed description of Sample Handling steps, standardized titration operation process and end point judgment. According to this standard, the nitrogen content can be accurately determined, providing key data support for vanadium-nitrogen alloy quality control and iron and steel smelting process optimization.
