铬铁合金中铬含量分析方法的改进

Ammonium Persulfate Oxidation Titration Method Measuring Chrome Content in Ferrochrome Alloy

铬铁系由铬和铁组成的铁合金,是炼钢的重要合金添加剂。对于这种铁合金中铬含量的测定,我们通过参照资料及实验,确定了用过硫酸铵氧化滴定法测定铬铁中的铬含量。此方法操作简便,分析周期短且重现性和准确性较高,适用于批量生产检验和仲裁检验。

Ferrochrome,a kind of iron alloy composed of chrome and iron,is an important alloy additive.For the chrome content determination of such a kind of iron alloy,we are determined to adopt Ammonium persulfate oxidation titration method through the reference material and experiments,.This method has the advantages of easy operation,short analysis cycle and high accuracy and reproducibility,and is suitable for the batch production test and arbitration inspection.
