| 摘 要： | 硫酸钴中铁的测定主要问题是存在钴基体对测定方法严重干扰。本文提出了在约7mol／L盐酸介质中，用乙酸乙酯萃取与钴分离，然后用水反萃取，在（1＋19）的盐酸介质中，以空气-乙炔火焰，于原子吸收光谱仪波长248．3nm处测定。本文还对方法的精密度和准确度等作了考查，结果令人满意。

| Abstract: | The methods are interfered badly by cobalt in determination of iron in cobalt sulfate.But the cobalt is extracted and separated with acetic ester in 7 mol/L chlorhydric acid medium in this method,and then anti-extract with water,the iron is determined in 248. 3 nm wave length of atomic absorption spectrograph with air-ethine flame in (1+9) chlorhydric acid mediun.The precision and accuracy of this method are inspected and the results are satisfied. |
