摘要
目的:建立电感耦合等离子发射光谱法(ICP-OES)测定灵芝中重金属及有害元素的方法并比较不同产地灵芝中的Cu、Pb、As、Cd、Hg等5种元素的含量。方法:采用恒压消解罐消解法处理灵芝供试品,用ICP-OES测定不同产地灵芝中Cu、Pb、As、Cd等4种有害元素的含量,氯化亚锡还原处理后在测汞仪上测定Hg。结果:5种元素线性关系良好,r在0.9928～1.0000;回收率在80%～120%;RSD均小于20%,符合痕量分析中小于30%的要求。结论:本法灵敏度高,准确度和重复性好,可作为灵芝中重金属及有害元素的定量测定方法。
Objective： To establish a method for the determination of 5 elements（Cu,Pb,As,Cd,Hg） in Ganoderma by inductively coupled plasma optical emission spectrometry（ICP-OES）,and determined samples grown in different areas. Methods： 4 elements of the digested samples were determined by ICP-OES simultaneously,and the contents were calculated by calibration curves.Hg determined by Mercury Analyzers .Results： Good linearity of calibration curves was obtained,the accuracy and the recovery met the requirement of trace analysis. Conclusion： The method is highly sensitive, with good accuracy and repeatiblity.
