Abstract

After the microwave digestion,As,Pb,Cr,Cd,Cu and Hg in Guijiajiao were determined by inductively coupled plasma mass spectrometry(ICP-MS).Especially,As was determined by collision cell technodogy.The detection limit ranges of the 6hazardous elements were 0.009-0.036ng/mL.The average recoveries of the 6elements were in the range of 85.1%-113.6% with the relative standard deviations less than 10%.The method is simple,rapid and accurate.It can be used to determine the contents of 6hazardous elements in Guijiajiao.
