摘　　要：利用微波消解-火焰原子吸收光谱法(FAAS)测定了大连产5种海藻样品中Zn、Fe、Cu、Mn4种微量元素的含量。对微波消解条件和原子吸收光谱测定的条件进行了优化。实验结果表明,微波消解法操作简便快速、样品消解完全,空白值低、环境污染小;火焰原子吸收光谱方法选择性好,准确度高,回收率为91%—105%。样品测定结果显示海藻中富含Zn、Fe、Cu、Mn4种微量元素,不同海藻微量元素含量存在差异。Four kinds of microelements were detected by microwave digestion-FAAS.The Conditions of determination were optimized.The result shows that the method of Microwave is easy,rapid and accuracy,and has advantages of complete digestion of samples,low-value blank and less environmental pollution.The recoveries of certified reference were in the range of 91%—105%,which was in good agreement with the certified value of certified reference.The result shows that accumulations of iron,zinc,copper and manganese in algae are rich,but different.
