大气气溶胶中痕量贵金属元素Pt的仪器中子活化分析初步研究

Preliminary studies on determination of trace platinum in aerosol particles by instrumental neutron activation analysis

初步研究了仪器中子活化分析方法测定大气气溶胶中痕量Pt的干扰,建立了Ca对Pt干扰校正的数学方法。实验结果显示:所建立的用199Pt衰变子体199Au测定大气气溶胶中Pt的INAA方法是可行的。

The interferences in determination of trace element Pt in aerosol particles by instrumental neutron activation analysis were preliminary studied. The mathematical correction method was used to correct the interference contribution of Ca in Pt determination. The results of this study show that the mathematical correction method is reliable.
