火焰原子吸收光谱法快速测定西酞普兰中的微量铜

Rapid Determination of Trace Copper in Citalopram by Flame Atomic Absorption Spectrometry

研究了硝酸-乙醇-水介质中,用空气-乙炔火焰原子吸收光谱法测定西酞普兰中微量铜的方法。结果表明,在最佳实验条件下,铜的线性范围为0.01—0.50μg/mL,相关系数(r)0.9996,检出限0.0052μg/mL。用本方法测定西酞普兰中的铜,加标回收率97%—104%。

A method for determination of trace copper in citalopram spectrometry was developed in a medium of nitric acid-etha by air-acetylene flame atomic absorption nol-water. Experimental results showed that the linear range of copper was 0. 01-0. 50μg/mL and the correlation coefficient （r） was 0. 9996 with a detection limit of 0. 0052μg/mL. The method has been used for the determination of copper in the citalopram that the recovery was 97%-104%.
