| Abstract: | The contents of Ca,Fe,Cu,Mn and Zn were determined by flame atomic absorption spectrometry(FAAS) with microwave digestion.There were abundant five elements,however,the contents of the same element in different varieties of yam were much more different.The recoveries of elements were between 94.5% and 104.0%.This method is simple and accurate with satisfactory results,and is an perfect method for detecting trace elements in yam. |
