石墨炉原子吸收光谱法测定土壤中铅的含量OA
Pb Determination in Soil Samples by Graphite Furnace Atomic Absorption Spectrometry
建立石墨炉原子吸收光谱法测定土壤中的微量铅的分析方法。用硝酸·盐酸-高氯酸体系进行土壤样品前处理，对试样分解、灰化及原子化温度进行选择，优化仪器工作参数及石墨炉升温程序。方法检出限为0．27μg／g，加标回收率为91．0％～96．1％，并利用国家标准物质验证了方法的准确度。
Objeetive：A method was established to determine the micro -amount of lead in soil by graphite furnace atomic absorption spectrometry. Methods： The soil samples were pretreated with nitric acid- hydrofluoric acid-perchloric acid pre-treatment system, by adding diammonium phosphate matrix modifier to eliminate interference, by optimizing equipment operating parameters and graphite furnace temperature pro- gram to explore the different acid-soluble systems, mat…查看全部>>
