蒽油中金属钠、铁和铜含量测定原子吸收光谱法的研究

Determination of Sodium、Iron and Copper content in Anthracene Oil- Atomic absorption spectrometric method

试样在蒸发皿中,先用小火慢慢加热灰化,至大部分挥发物挥发后,将蒸发皿置于高温炉中灰化后,用盐酸溶解,采用火焰原子吸收光谱法测定蒽油中的钠、铁和铜含量。实验表明,钠、铁和铜含量在0～5 mg/L范围内线性关系良好,相关系数γ=0.999,该法回收率93%～104%,能满足进出口蒽油检验的要求。

The samples were in the crucible,then heated it slowly with softfire and ashed it ,after evaporated of most of evaporating matte~ ,put the crucible in the oven and ashed it,then disolved it with HCI solution. Determination fo Sodium,Iron and Copper content in Anthracene Oils with Atomic AbsorPtion Spectrometric Method （ Flame Method ）.The result shows,in the range of 0-5mg/1,the liner relation of the content of Iron and Copper is good,corresponding factor u =0.999,and its recovery ratio is 93- 104%,can make the requirement of the inspection of Import and Export Anthracene Oils.
