样品通过王水溶剂在水浴消解,在同一溶样体系中,以硼氢化钾作还原剂将被测元素转化为在室温下呈气态的氢化物,以高纯氩气作为载气将气态氢化物引入到特殊设计的石英炉中,并在此原子化,受铅、铋特种空心阴极灯光源的激发,铅、铋原子辐射出原子荧光,根据荧光强度与溶液中待测元素的浓度成正比的关系测试铅、铋。
Samples were digested by aqua regia in a water bath. In the same solution system, potassium hydride was used as a reductant to convert the analyte into a hydride which is in a gaseous state at room temperature. High purity argon gas was used as a carrier gas to transport the gaseous hydride Introduced into a specially designed quartz furnace and atomized by this, excited by lead and bismuth special hollow cathode lamp light source, the atomic bismuth atoms radiate atomic fluorescence, and the fluorescence intensity is proportional to the concentration of the element to be measured in the solution Relationship testing lead, bismuth.
