摘　　要：采用高温灰化样品,火焰原子吸收分光光度法(FAAS)和电感耦合等离子体原子发射光谱法(ICP-AES)测定偏苯三甲酸酐(TMA)中铁的含量。在仪器最佳工作条件下,FAAS法和ICP-AES法的加标回收率分别为94.6%和95.7%,对两个不同批号样品的检测结果基本一致。Iron content in TMA, by FAAS and ICP-AES were described in the paper. Samples were ashed at 600 ℃ in an oven. Under the optimum conditions, the values of recovery of FAAS and ICP-AES were 94.6 % and 95.7 %, respectively. Two different samples results detected by ICP-AES were consistent with those detected by FAAS.
