摘　　要：采用微波密闭消解电感耦合等离子发射光谱法(ICP-AES)对鸡肌肉中K,Ca,Na,Mg,P,S,Fe,Cu,Mn和Zn等12种无机元素含量进行了测定。采用HNO3-H2O2混合酸溶体系对待测样品进行消解。结果表明该方法的相对标准偏差均在5%以下;通过添加标准回收实验,回收率在92.5%～110%。与传统方法相比,该方法具有良好的准确度和精密度,高度灵敏性,能同时测定多种元素等优点,可满足样品检测要求,可为鸡肌肉无机元素快速检测提供科学依据。The contents of inorganic elements including K, Ca, Na, Mg, P, S, Fe, Cu, Mn, Zn, Mo, and Co from the chicken muscle were determined by ICP AES using sealed microwave digestion. The sample of the chicken muscle was digested with HNO3-H2O2 system. The relative standard deviation was less than 5% for all the elements, and the recovery was 92.5%-110% by adding standard recovery experiment. This method was simple, sensitive and precise and can perform simultaneous multi-elements determination compared with conventional method of the chicken muscle determination, which could satisfy the sample examination request and provide scientific rationale for determining inorganic elements of chicken meat.
