摘　　要：目的：建立海带中6种金属元素的火焰原子吸收测定方法。方法利用微波消解处理海带样品，使用火焰原子吸收法测定海带中钙、镁、铁、锌、铜和锰。结果海带中含有丰富的金属元素，实验回收率为95.5％～108.2％，样品进行5次平行测定， RSD为1.22％～4.25％。结论该法具有快速、简便、灵敏、准确的优点，适用于海带中6种金属元素的测定。Objective To establish FAAS method for determining 6 metal elements in laminaria .Methods Microware digestion was used to dispose the samples; FAAS method was applied to determine Ca , Mg, Mn, Fe, Zn and Cu in laminaria .Results There are rich content of metal elements in laminaria , the average recovery rate was 95.5%~108.2%, the RSD in the 5 determinations was 1.22%~4.25%. Conclusion This method is rapid, simple sensitive and accurate , it is applicable for the determination of 6 metal elements in laminaria .
