火焰原子吸收光谱法测定煤矸石中铜的样品前处理技术改进

Improvement of Sample Pre-Treatment Technology for Determining Copper in Coal Gangue by Flame Atomic Absorption Spectrometry

摘要: 采用火焰原子吸收光谱法测定了煤矸石中Cu的含量. 研究了实验预处理技术、消解体系的控制选择及仪器条件的优化,建立了相应的原子吸收光谱测定方法. 方法的RSD在1%~3% 之间,加标回收率达到96.5%~104%.

Abstract: Determination of copper in coal gangue was analyzed by flame atomic absorption spectrometry. The method of sample pretreatment was reserched, digestion conditions and instrument conditions were optimized, the corresponding determination of atomic absorption spectrometry was established. RSD of the method was between 1% to 3%,the recovery was 96.5%~104%.
