| 摘 要： | 用电感耦合等离子体质谱法（ＩＣＰ—ＭＳ）测定了５个黄沙原土样品中铅同位素比２０７Ｐｂ／２０６Ｐｂ、２０８Ｐｂ／２０６Ｐｂ，样品来自被认为是黄沙气溶胶源地区，为了使铅同位素测量中质量偏差和漂移减至最少，在样品中加入了铊标准溶液，测量２０５Ｔｌ／２０３Ｔｌ比，校正质量数差别选择的影响．同时，采用ＩＣＰ—ＭＳ和电感耦合等离子体原子发射光谱法（ＩＣＰ一ＡｌＳ）测定了随粒径变化样品中１２种元素浓度的变化．

| Abstract: | Five original KOSA soils,collected in the locations of being thought to be the origins of KOSA aerosol in China,were analyzed by inductively coupled plasma mass spectrometry (ICP-MS) to determine the lead isotope ratios 207Pb/206Pb and 208Pb/206Pb.Tominimize mass bias and drift in Pb isotope measurement,the mass discrimination correction,based upon the addition of thallium to the samples and measurement of 205Tl/203Tl ratio,was used.At the same the, concentrations of 12 elments were determined as a function of particle-size by ICP-MS and induedvely coupled plasma atomic emission spectrometry (ICP-AES). |
