摘要

In this paper, a hydride generation atomic fluorescence spectrometry method was used to determinate the trace arsenic, selenium and mercury in fructus mume, The samples were digested by microwave. Under the optimum condition, the quantities of three interference elements were detected, The detection limits were as fellow: As:0.12 ng/mL, Hg:0.066 ng/mL, Se:0.25 ng/mL, the linear ranges were: As:0-100 ng/mL, Hg:0~40 ng/mL, Se:0-80ng/mL, linear equations:As:If=3.86C-7.86, r=0.9997, Hg:If=104.41C-0.42, r=0.9990, Se:If=0.3686C+0.5, r=0.9994(C: ng/mL), the recoveries are breween 97.6%~101.8%, the method is simple, rapid and accurate.
