摘　　要：用微波等离子体炬（MPT）-原子发射光谱（AES）测定镍基合金中的铁含量，考察了仪器工作条件、酸度影响和共存离子的干扰，使用基体匹配法消除基体干扰。结果表明，测定铁的线性范围为0.01-100μg/mL，检出限为18.96ng/mL，RSD（n=11）为3.65%。方法测定结果与国家标准方法测定结果相符合，方法具有准确、简便、快速的特点，适用于镍基合金中铁元素的分析测定。The determination of iron in the niekel base alloy by mierowave plasma toreh（ MPT）-atomie e-mission speetrometry（ AES）method was studied. The seleetion of instrument working eonditions,the effeets of aeidity and the interferenee of eoexisting ions were investigated,using the matrix matehing method to eliminate the matrix interferenee. Determination of iron linear range was 0. 01 - 100μg/mL,detee-tion limits were 18. 96 ng/mL,RSD（n = 11）was 3. 65%. The determination result of MPT-AES is eon-sistent with the national standard method,the method is aeeurate,simple and fast,suitable for the niekel base alloy of iron element analysis determination.
