摘　　要：本文提出微波高压消解-火焰原子吸收光谱法(AG-FAAS)测定食用菌中痕量铜、锌、铁和锰的方法.该方法检出限Cu2+、Zn2+、Mn2+为:1.0×10-9g/mL和Fe3+为:5.0×10-9g/mL.Mn2+、Fe3+Cu2+和Zn2+的含量分别在0.250～4.000、0.500～2.500、0.100～0.500和0.300～1.500μg/mL范围内符合比尔定律,相关系数为0.9997～0.9999.此法用于茶树菇、香菇中铜、锌、铁和锰含量的测定,结果令人满意.An advanced microwave sample digestion method is described for the determination trace elements of Cu 、Zn、 Fe、Mn in different part of the lentinus edodes and A-groeybe chaxingx sample by flame atomic absorption spectrometry to reveal the relation between the curative effect of edible mushroom and the trace elements. The linear dynamic range of this method is 0.250～4.000、0.500～ 2.500、0.100～0.500(Mn2+、Fe3+ Cu2+) and 0.300～1.500(Zn2+)μg/mL according to Beer Law with a detection limit (L.D.) of 1.0×10-9 (Cu2+、Zn2+、Mn2+) and 5.0×10-9g /mL (Fe3+), respectively.The proposed method was proved to the simple rapid,accurate and reliable had been applied to the analysis of the samples with satisfactory results.
