微波消解-电感耦合等离子体质谱法测定八角中9种重金属元素
Determination of Nine Heavy Metal Elements in Aniseed Inductively Coupled Plasma by Microwave Digestion-mass Spectrometry
摘要
Abstract
A method was established to for the analysis of Hg,As,Cd,Pb,Cr,Ni,Cu,Mn and Ba in anise by using inductively coupled plasma-mass spectrometry(ICP-MS).According to the content of each element in the anise sample to determine its linear range,The standard series concentrations of each element were 0-3 µg/L(Hg),0-10 µg/L(As,Cd,Pb),0-100 µg/L(Cr),0-200 μg/L(Ni,Cu,Ba),0-5000 μg/L(Mn).The correlation coefficient R2 of the linear equation is greater than 0.9994.The detection limits of each element were 0.004-0.095 mg/kg.The results of pollen GBW10026(GSB-17)were all within the range of standard values.The method is rapid,sensitive and accurate for the determination of various heavy metal elements in anise.关键词
