| 摘 要： | 在青海低氧低分压环境下,试样用王水分解,在王水介质中用多孔聚氨酯泡沫振荡吸附富集,然后用硫脲加热解脱,再直接用火焰原子吸收分光光度计测定。通过对泡塑的吸附振荡,解脱时间,硫脲浓度等条件的探讨,确定了最佳分析条件,解决了低氧低分压环境下常量A u的测定。

| Abstract: | Under the hypobaric hypoxia condition in Qinghai areas,the samples were digested with aqua regia and enriched by polyurethane foam in the aqua regia,then heated to liberate in the solution of thiourea,finally directely measured by flame atomic absorption spectrometry.The conditions of polyurethane foam adsorption oscillation,free time,the concentration of thiourea were discussed.The method was optimized,and that is applied to the determination of gold in Qinghai areas. |
