基　　金：微波消解-等离子体发射光谱法测定燃香可迁移元素含量(FJQI2017038);本草香燃烧产生的多环芳烃及重金属元素排放特征研究(2019N030)。

摘　　要：采用稀盐酸萃取处理样品,通过ICP-OES测定燃香类产品中重金属As、Cd、Cr、Pb、Hg元素含量。5种元素检出限在0.034-0.54mg/kg之间。除Hg元素之外,相对标准偏差(RSD)<5.38%,回收率为85.8-102%。80%燃香类产品的Cr元素含量最高,Pb元素含量次之。ICP-OES能够高效准确地检测燃香类产品中的多种重金属元素,为燃香类产品的质量评价和安全使用提供参考意义。The heavy metals(As,Cd,Cr,Pb,Hg)in incense was determined by ICP-OES after hydrochloric acid extrac tion.The detection limits of five elements are between 0.034 and 0.54mg/kg.With the exception of Hg,the relative standard deviation(RSD)is less than 5.38%,and the recovery is 85.8-102%.The Cr content of 80%incense was the highest,fol lowed by Pb content.ICP-OES can efficiently and accurately detect various heavy metal elements in incense,providing valuable reference for quality evaluation and safety of incense.
