| Abstract: | 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. |
