摘　　要：建立了一种灵敏准确的测定海产品中总锡含量的分析方法。利用微波消解对样品进行前处理,采用在线内标(103 Rh)校正基体效应和仪器漂移,电感耦合等离子体质谱法(ICP-MS)进行测定,方法检测限为4.8μg/kg,加标回收率为85.0%～106%,相对标准偏差<10%。该法可用于章鱼、墨鱼、带鱼、海参、海带、紫菜等海产品的测定。A sensitive and accurate method for the determination of total tin in seafood has been developed. After the microwave digestion, the samples were directly analysed by inductively coupled plasma mass spectrometry（ICP-MS）,^103Rh was used as on-line internal standard to correct the matrix interference and the instrument drift. The detection limit was 4. 8 μg/kg, the average recoveries were between 85.0%o -106 % with the relative standard deviations〈10 %. The proposed method has been applied to the determination of total tin in octopus, cuttle, hairtail, sea cucumber, kelp and laver with satisfactory results.
