摘　　要：采用微波消解-电感耦合等离子体-原子发射光谱仪测定了五香粉中Cu、Zn、Fe、Mn、Cd、Pb6种重金属元素的含量。结果表明,五香粉中Cu、Zn、Fe、Mn等人体必需微量元素含量丰富,而对人体有害的Cd和Pb含量较少。该方法的加标回收率在95.0%—106.3%之间,相对标准偏差小于3%,具有较好的准确度和精密度。The contents of six heavy metals including Cu,Zn,Fe,Mn,Cd and Pb in five spices powder were determined by inductively coupled plasma-atomic emission spectrometry（ICP-AES） with microwave digestion. The results showed that the contents of Cu, Zn,Fe and Mn were rich,and the levels of Cd and Pb were low. The recoveries were between 95.0% and 106. 3%, and the relative standard deviations were below 3 M with good accuracy and precision.
