ICP-AES和AAS法在苔藓植物重金属含量测定中的应用

Application of ICP-AES and AAS in measuring the contents of heavy metal in bryophytes

采用微波消解样品I、CP-AES和AAS法对鳞叶藓中的Cu、Mn、Fe、Zn、Cd、Cr、Ni、Pb的含量测定进行了探讨和比较.测得结果的准确度和精密度均令人满意.且两种方法所测得的Pb含量无明显差异(P>0.05).

The contents of eight elements （Cu,Mn,Fe,Zn,Cd,Cr,Ni,Pb） in Taxiphyllum taxirameum （Mitt） Fleisch. were measured by microwave digestion, ICP-AES and AAS. The accuracy and precision of the measured results were all satisfying, and the contents of Pb measured by ICP-AES and AAS had no obvious difference （P 〉0.05）.
