利用冰醋酸作溶剂，采用火焰原子吸收光谱法直接测定氢甲酰化反应液中的总铁含量。以1mol/L盐酸萃取样品，有机相与无机相分别用冰醋酸稀释后用火焰原子吸收法测定，可分别得到样品中有机铁与无机铁的含量。方法简便、快速、可靠，具有较好的精密度和准确度。回收率为93.5%—109%，相对标准偏差为1.0%—2.7%，方法的特征浓度为0.585μg/mL/1%。

Using acetic acid as the solvent, the total iron concentration in hydroformylation reaction liquid was directly determined by flame atomic absorption spectrometry. By 1mol/L HCl as extraction agent and acetic acid as solvent, organic and inorganic iron were quantitatively separated from hydroformylation reaction liquid and determined by FAAS. The method was proved to be simple, rapid, precise and convenient . The recovery is from 93.5% to 109%.The relative standard deviation (RSD)is in the range of 1.0%—2.7%. The characteristic concentration of the method is 0.585μg/mL/　1%.
