Determination of Eight Mineral Elements in Potentilla Anserina L. by Microwave Digestion-FAAS

Eight mineral elements of K,Na,Ca,Mg,Cu,Zn,Fe,Mn in potentilla anserina L.were determined by flame atomic absorption spectrometry (FAAS).The method of the sample pretreatment,choice of the instrumental determination conditions,and interference with its elimination of the coexisting elements were invesitigated.Furthermore,the addition standard recovery tests of each element were also done.The relative standard deviation is below 2.5%(n=8),and the addition standard recovery is in the range of 96.5%—103.2% for all the elements under given conditions.
