火焰原子吸收光谱法测定电积铜浸出液中铜和铁

在硫酸介质中,以铜和铁的次灵敏吸收线249.2 nm,302.1 nm为吸收波长,用空气-乙炔火焰原子吸收光谱法测定了电积铜浸出液中铜和铁。对仪器工作条件、硫酸及共存离子的干扰情况等进行了试验。方法用于电积铜浸出液中铜和铁的测定,相对标准偏差为3.3%,1.9%;回收率在96.5%-105.0%之间。方法简单,可用于日常分析。

Determination of copper and iron in electrodeposited copper lixivium by flame atomic absorption spectrometry

In the medium of sulfuric,a analytical method for determining copper and iron in electrodeposited copper lixivium by flame atomic absorption spectrometry was studied.The analytical spectrum lines of copper and iron were selected as 249.2 nm and 302.1 nm,respectively.The working conditions of instrument were optimized and the influences of the volume of sulfuric acid,coexisting ions were tested as well.The method has been applied to analyse copper and iron in electrodeposited copper lixivium with the recoveries of 96.5%-105.0%,and the relative standard deviations of 3.3% for copper,1.9% for iron.The method is simple,accurate and suitalbe for the routine analysis.
