王水回流消解同时测定土壤/沉积物中汞、砷和镉的方法研究
Determination of Mercury, Arsenic and Cadmium in Soils/Sediments with the Refluxing Digestion of Aqua Regia
摘要
Abstract
Hg, As and Cd in soil/sediment samples were determined with the refluxing digestion of aqua regia. Cd was determined by Graphite Furnace Atomic Absorption Spectrometry. Hg and As were determined by Atomic Fluorescence Spectrometry. 8 geochemical standard reference material of soil/sediment were tested. The test data showed that the determination of standard reference material were within the reference range. The relative standard deviation of Hg, As and Cd were 2.9％～8.2％,1.2％～5.6％ and 3.4％～6.8％. The detection limit, precision and accuracy of the methods met the requirements of the determination of soil.关键词
