Determination of Trace Elements in Three Types of Scented Tea by Flame Atomic Absorption Spectrometry

Shurong Wang

Abstract

The sample was treated by HNO3-HCIO4 system and nine trace elements of Ca,Mg,Fe,Zn,Cu,Mn,Sr,Na and K in three types of scented tea by flame atomic absorption spectrometry.The standard relative curve coefficients of ten kinds of ten trace elements range from 0.9983～0.9999,the recovery in the range of 97.40%～103.00%,and the RSD 0.81%～3.47%.The method has good precision and sensitivity.
