Abstract:
Objective To establish a method for the determination of Fe, Cu, Zn, Mn in the pollen by flame atomic absorption spectrometry(FAAS).Methods Wet digestion-flame atomic absorption spectrophotometry was used to determine the content of Fe, Cu, Zn, Mn in the pollen.Results In the selected experimental conditions, the recovery rates of these elements were 98.5%-103.0% and the coefficient of variation was 1.13%-2.36%.The detection limits were 0.40 ?g/L for Fe, 0.08 ?g/L for Cu, 0.20 ?g/L for Zn, 0.14 ?g/L for Mn.The linear range was 0.00-2.00 mg/L.Conclusion FAAS is simple, fast, accurate for the determination of Fe, Cu, Zn, Mn in the pollen.
