ABSTRACT Objective: To determine the contents of nine kinds of inorganic elements in Gansu area.Method: A flameatomic absorption spectrometry with airacetylene flame was adopted.Result: Nine kinds inorganic elements contents distributed tendencies which measured were the contents of K, Na, Ca, Mg, Fe, Zn elements in Longnan, Tianshui area was relatively high and that of Cu, Cr, Mn elements in places such as Lanzhou,Tianshui was relatively high.Conclusion: The contents of inorganic elements is obvious for region influence.
KEY WORDS Ginkgo leaf; inorganic elements; atomic absorption spectrometry.
