原子吸收测定铜精粉中铜的含量

Atomic Absorption Determination of Copper Content in Copper Concentration Powder

摘要:

铜精粉中铜的含量一般在30%左右，其中碘量法被列为铜精矿测定铜的国家标准方法，火焰原子吸收光谱法测定铜普遍应用于低含量铜的测定，测定范围一般为0.001%～5%，该文通过王水分解样品，分取稀释，在2%的盐酸介质中，用高浓度标准系列原子吸收快速测定铜精粉中铜的含量，该法简便快速，选择性好，准确度高。

Abstract:

The copper content in copper concentration powder is generally 30%. Iodometric determination of copper concentrate has been listed as national standard methods. Flame atomic absorption spectrometry determination of copper content is generally applied to determing low content copper. Its measuring range is generally 0.001%~5%. In this paper, samples have been decomposited by aqua regia and diluted, in 2% hydrochloric acid medium, using a high concentration standard series atomic absorption rapid determination method, copper content of copper concentration powder has been determined. This method is simple, rapid with good selection and high accuracy.
