摘要
目的建立微波消解电感耦合等离子体质谱法同时测定鱼油类保健食品中铝、镉、总铬、铜、锌、镍的含量。方法采用微波消解法处理样品,电感耦合等离子体质谱法测定。结果 6种元素中在0~100 mg·L-1范围内,线性关系良好。平均加样回收率在98.8%~105.2%之间,精密度RSD在1.6%~2.8%,重复性RSD在0.66%~4.91%。结论本方法简便快速准确,可用于鱼油中6种微量元素的测定,为国家保健食品监督抽验和风险监测工作提供技术支持。
Objective To establish an ICP-MS method for the determination of aluminum,cadmium,total chromium,copper,zinc and nickel in fish oil health food.Methods Samples were determinated by microwave digestion and inductively coupled plasma atomic emission spectrometry.Results The calibration curve of 6 elements were linear in the concentration range of 0 ~ 100 mg·L-1.Standard addition recovery rates were 98.8% ~ 103.4% on average,the RSDs of precisions were in1.6% ~ 2.8%,the RSDs of repeatabilities were in 0.66% ~ 4.91%.Conclusion This method was simple,rapid and accurate for the determination of fish oil health food in 6 elements,and can provide technical support for the national health food supervision,testing and risk monitoring.
