含铜铁矿石全铁的测定时铜对铁的影响探讨

Influences Discussion of Copper on Iron in Determination of Total Iron in Containing Copper Iron Ore

探讨了含铜铁矿石分析过程中的铜对铁分析的影响。分析过程中采用标准溶液模拟实验、国家标准物质中铁的容量分析、方法比对等实验,得出一个大约的经验系数R,为含铜铁矿石中全铁含量的质量控制提供参考。该系数经过对多个含铜国家标准物质中的铁进行分析验证,样正值与标准值基本相符。

The Influences of copper on the analysis of iron in process of analyzing the containing copper iron ore were studied.Imitate experiment of the standard solution,volumetric analysis and method comparision of iron in national standard material were adopted in analysis process,then an approximate experience coefficient（R） was obtained,that provided reference for quality control of the content of total iron in containing copper iron ore.The coefficient is analyzed and verified by iron in the multiple containing copper national standard materials,and the sample values confirmed to standard values.
