| Abstract: | The trace elements of K,Na,Mg,Ca,Fe,Zn,Cu,Mn in guava are determined by using flame atomic absorption spectrophotometry.The relative standard deviations(RSDs) of the methods are within 0.65%-2.3% and the recoveries obtained are in the range from 97.6% to 103%.As a result,it has been proved that the trace metal elements are abundant in guava.The method is convenient,rapid and accurate. |
