浅析硫酸亚铁铵滴定法测定钒氮合金中钒

Determination of Vanadium in Vanadium Nitrogen Alloy by Ammonium Ferrous Sulfate Titration

摘要

随着公司极致高效的发展步伐，对日常检验工作的要求也越来越高，论文中的方法以国标方法为基础，对钒氮合金中钒含量的化学湿法分析方法进行研究开发，通过对国标方法中一些步骤在现有实验室条件下进行适合本实验室的优化和简化，并组织进行大量试验分析比对，以数据验证方法的可行性。结果表明，此方法分析结果准确，与国家标准物质认定值最大偏差仅0.16%；分析精确良好，相对标准偏差在0.092%~0.166%，且操作简单快速，能满足公司的检验要求。

Abstract

With the company’s extremely efficient development pace, the requirements for daily inspection work are getting higher and higher. Based on the national standard method, the chemical wet analysis method of vanadium content in vanadium-nitrogen alloy is studied and developed in this paper. Some steps in the national standard method are optimized and simplified under the existing laboratory conditions, and a large number of experimental analysis and comparison are organized to verify the feasibility of the method. The results showed that the analysis results of this method were accurate, and the maximum deviation from the certified value of national standard substance was only 0.16%. The analysis is accurate and good, the relative standard deviation is between 0.092% and 0.166%, and the operation is simple and fast, which can meet the inspection requirements of the company.
