摘　　要：目的：研究面制食品中硼和铝的ICP-AES（Inductively Coupled Plasma-Atomic Emission Spectrometry）测定法。方法：采用微波消解样品,于ICP-AES上同时测定消解液中硼和铝的含量。结果：硼、铝元素的相关系数分别为0.9999和0.9998,线性范围分别为0.2～100 mg/kg和0.5～100 mg/kg,RSD〈3.0%,回收率92.8%～103.6%,该法测定铝的结果与国标方法-铬天青S分光光度法比较,差异无统计学意义（P〉0.05）。结论：该方法快速、准确、简便、干扰少,适合面制食品中硼和铝的测定。Objective： To develop a new method of Inductively Coupled Plasma-Atomic Emission Spectrometry for determination of B and Al in food.Methods：The sample was digested by microwave and the elements of B and Al were determined with ICP-AES.Results：The linear range of method was B（0.2～100）mg/kg,Al（0.5～100）mg/kg（r〉0.9998）.The RSD was not more than 3.0%.The recovery rate was 92.8%～103.6%.Conclusion：This method is rapid,accurate and simple,and is acceptable in determination of B and Al in food.
