微波消解ICP-MS法测定紫菜中微量重金属元素

Determination of Trace Heavy Metal Elements in Laver by Microwave Digestion and Inductively Coupled Plasma Mass Spectrometry

采用密闭微波消解法消解紫菜样品,在优化微波消解条件的基础上,建立微波消解ICP-MS法同时测定紫菜中Al、As、Ba、Cd、Co、Cr、Cu、Fe、Mn、Ni、Pb和Zn十二种微量重金属元素的方法。

The method for the determination of AI,As,Ba,Cd,Co,Cr, Cu,Fe,Mn,Ni,Pb and Zn in Laver by microwave digestion and inductively coupled plasma mass spectrometry has been presented. Microwave digestion conditions and operational conditions of ICP-MS were optimized.
