| 摘 要： | 目的:研究干香菇中的微量元素及重金属,建立最佳测定条件。方法:采用微波消解,原子吸收分光光谱法测量样品中所含有的Pb、Zn、Cu、Cr、Cd 5种微量元素的含量,均采用石墨炉原子化器,并做了相关的方法学考察。结果:测量结果显示样品中Zn、Cr、Cu 3种有益微量元素均有较丰富的检出;其他两种重金属元素(Pb、Cd)含量均超出国家标准和欧盟法规中香菇重金属限量。结论:方法简便,准确,可较好地用于干香菇中微量元素的含量测定。

| Abstract: | Objective: To determine the content of five trace elements(Pb,Cd,Cu,Zn,Cr)in Lentinula edodes.Methods: This experiment choose the different Lentinula edodes from the different source,adopted the method of microwave digestion-AAS to establish the detection of the microelement in Lentinula edodes.Results: Zn,Cr and Cu in the Lentinula edodes is rich;the other two heavy metal(Pb、Cd)exceed standard.Conclusions: The method is simple and accurate,and can be used in the determination of trace elements in Lentinula edodes. |
