通过实验 ,制定了用有机溶剂萃取 ,火焰原子吸收光谱法同时测定水样中铜、铅、锌、镉、铁、锰、镍、钴八种微量元素的方法。实验证明该方法重现性好 ,准确度高 ,相对标准偏差小于 7 0 % ,水样加标回收率为 89～ 110 %。 Through experiment, the method of simultaneous determination of eight trace elements of copper, lead, zinc, cadmium, iron, manganese, nickel and cobalt in water by flame atomic absorption spectrometry was developed by organic solvent extraction. Experiments show that the method has good reproducibility, high accuracy, relative standard deviation less than 70%, and spiked water recovery of 89 ~ 110%.
