摘    要:建立了同时测定食用明胶中铅、铬和砷的新方法。试样经微波消解后用端视电感耦合等离子体原子发射光谱(ICP-AES)法同时测定。对仪器的工作参数进行了优化和选择。铅、铬和砷的检出限分别为0.002,0.000 8,0.004 mg/L;定量限分别为0.066,0.026,0.13 mg/kg。相对标准偏差为0.89%~2.71%,回收率为94.0%~106.0%。该法操作简便、快速,结果准确,适用于食用明胶中铅、铬和砷的快速测定。

关 键 词:微波消解  端视ICP-AES  食用明胶

Abstract:A new method for the simultaneous determination of Pb,Cr,and As in edible glutin was established.Samples were digested with microwave and determined by axial view ICP-AES.The plasma parameters were optimized and selected.The detection limits of Pb,Cr and As were 0.002、0.000 8 and 0.004mg/L.The LOQ was 0.066、0.026 and 0.13 mg/kg.The relative standard deviations was 0.89%~2.71%.The recovery was 94.0 %~ 106.0 %.The method was simple,rapid,accurate and suitable for determination of Pb,Cr and As in edible glutin.
Keywords:microwave digestion  axial view ICP-AES  edible glutin  Pb  Cr  As
