过硫酸铵氧化容量法测定钢铁及合金中铬含量不确定度的评定

Assessment of the uncertainty in determining chromium content in iron,steel and alloys by means of oxidation volumetric method using ammonium persulfate

对过硫酸铵氧化容量法测定钢铁及合金中铬含量的不确定度的产生原因进行了分析,并对钢铁样品中铬含量测定结果的不确定度进行了评估和计算.

The factors responsible for the uncertainty involved in determining chromium content in iron, steel and alloys by means of oxidation volumetric method using ammonium persulfate were analyzed, and the uncertainty involved in determining chromium content in iron and steel assessed in the article.
