Determination of Trace Elements in by Flame Atomic Absorption Spectrophotometr (FAAS)
Objective:To develop a method of determination of trace elements in Fructus Forsythiae. Method: The content of Cu
Zn
Mn
Fe
Ca
Mg
K
Na in Fructus Forsythiae was directly determined by flame atomic absorption spectrophotometry after digestion with HNO3-HClO4(4:1) at heating and normal pressure. Result: All calibration curves showed good linearity (r>0.990 6). The RSD (n=6) of reproducibility was between 1.59% and 2.98%. The recoveries (n=6) were from 96.2% to 106.6%. The RSD (n=6) of recovery was between 1.4% and 3.9%. Conclusion: The method was simple
accurate and sensitivity. It is a reliable method for the determination of the trace elements in Fructus Forsythiae.
