HUANG Zhiwei,LI Zhongliang,WEI Qingmin (Department of Chemistry and Biology,Yulin Teachers College,Guangxi Yulin 537000,China)  
The content of Fe,Mg,Zn,Ca,Pb,Cd,Mn and Cu in Laver has been determined by microwave digestion-flame atomic absorption spectrometry.In this experiment,the rate of recovery is 97.0%~(102.2%),with relative standard deviation(RSD)≤1.82%,which suggests that the method is accurate and precise to determine these elements.The results also supply useful date of the relation of the metal elements in Laver and food healthcare.
