摘  要：
采用微波消解前处理,电感耦合等离子体质谱法(ICP-MS)测定部分香辛料中铅、砷、镉、铬、铜、锰、锌和镍的含量。测定结果显示各元素线性范围均为0～500ng/mL,线性方程相关系数均大于0.9995,各元素检出限在0.009～0.42ng/mL之间,相对标准偏差均小于5%,低、中、高质量浓度标准溶液加标回收率在88%～109%之间,选择的3种标准物质GBW08521、GBW(E)080684和GBW07605(GSV-4)的各元素测定值均在标准值范围之内,由此说明该方法能够简单、快速、灵敏、准确测定香辛料中重金属元素。

摘  要：
Inductively coupled plasma mass spectrometry(ICP-MS)with microwave digestion was applied to determine lead,arsenic,cadmium,chromium,copper,manganese,zinc and nickel in spices.The linear range of the developed ICP-MS method was from 0 to 500 ng/mL(r>0.9995).The detection limits were between 0.009 ng/mL and 0.42 ng/mL.The precision of the method was evaluated with a relative standard derivation(RSD)of lower than 5%,and the average recoveries in a sample spiked at three levels were in the range of 88%to 109%(n=11).The results of determining various elements in three standard reference materials of GBW08521,GBW(E)080684 and GBW07605(GSV-4)were all within the ranges of standard values.This method proves good simplicity,sensitivity and accuracy in the determination of heavy metal elements in spices.
