摘　　要：乌贼骨样品经高压消化罐消解,采用电感耦合等离子体原子发射光谱法（ICP-AES）和火焰原子吸收光谱法（FAAS）分别测定了样品中铁、锌、铜、锰、钙、镁、钴、镍、钾、铬、硅、铝、鉛和镉等14种微量元素的含量。结果表明：两种方法的回收率分别在96.5%-107.1%（FAAS）和96.7%-100.3%（ICP-AES）之间,相对标准偏差分别为0.7%-3.0%（FAAS）和0.2%-2.2%（ICP-AES）。经F法和t法检验,ICP-AES和FAAS测定微量元素含量的测定值之间无显著性差异。The sample of cuttlefish bone was digested under pressure,and the contents of trace elements,including Fe,Zn,Cu,Mn,Ca,Mg,Co,Ni,K,Cr,Si,Al,Pb and Cd,in the solution obtained were determined by ICP-AES and FAAS.The values of recovery and RSD′s（n=6） found were in the ranges of 96.5%-107.1%,96.7%-100.3% and 0.7%-3.0%,0.2%~2.2% for FAAS and ICP-AES respectively.By F-and t-test,it was found that the results obtained by the two methods showed no significant differences.
