摘　　要：采用微波消解处理样品,电感耦合等离子体发射光谱（ICP-OES）测定了发菜中微量元素Fe、Cu、Mn、Zn含量。结果表明,各元素检出限分别为1.58、0.79、0.52、0.67μg.mL1;相对标准偏差均小于2.2%;回收率为92.7%~101.3%。该法精密度高、准确度好,所测数据可为发菜的合理利用提供依据。Microwave digestion procedure and inductively coupled plasma optical emission spectroscopy（ICP OES）were used for simultaneous determination of Fe,Cu,Mn,Zn in Nostoc flagelliforme.The results showed that detection limits were Fe 1.58,Cu 0.79,Mn 0.52,Zn 0.67 μg·mL 1,relative standard deviations were less than 2.2%.The recoveries for the spiked samples ranged from 92.7%~101.3%.The method with high precision and good accuracy can be used for the determination of Fe,Cu,Mn,Zn in Nostoc flagelliforme samples.
