摘要
硝酸和高氯酸(4+1)分解样品,火焰原子吸娅光谱法测定3种海藻中铜、锰、锌微量元素含量。结果表明上述海藻均富含与人体健康密切相关的铜、锰、锌微量元素,且样品中各元素含量差异显著。其中裙带菜含量大小为:Cu〉Mn〉Zn,紫菜含量大小为:Cu〉Mn〉Zn,羊栖菜含量为:Zn〉Mn〉Cu,各元素RSD范围为0.42%~3.23%,各元素回收率在91.8%~109.2%之间。方法方便、简单快速。
Nitf tracerate and perchlorate (4 + 1 ) sample digestion, by flame atomic absorption spectroscopy determination of three kinds o elements in three kinds of copper, manganese and zinc in the seaweeds. Differences in trace elements in three kinds of seaweed, wakame element size is: Cu〉 Mn 〉 Zn, Laver in the element size is: Cu 〉 Mn 〉 Zn, Sargassum fusiforme in element content is: Zn 〉 Mn 〉 Cu, the relative standard deviation of 0.42 % - 3.23 %, the recovery rate is 91.8 % - 109.2 %.
