氢化物原子荧光光谱法是普遍使用和较为理想的分析As、Sb、Bi的方法之一。然而，在原子荧光光谱法测定As、Sb、Bi的过程中，影响因素很多。通过开展一系列实验全面分析氢化物发生-原子荧光光谱法测定As、Sb、Bi时常见的各种影响因素，包括试样的制备（如试样称样量、试样的分解方法、试液介质及酸度的选择、共存离子的影响及消除和试剂空白的影响）、高含量样品的污染问题及仪器工作条件（如负高压、载气及屏蔽气流量、观测高度和还原剂浓度）等因素，提出了相应的解决方法，得出合理的分析条件，为化探样品As、Sb、Bi的准确测定提供了可靠保证。

It is one of the generally and preferable methods to analysis As,Sb,Bi for the fluorescence spectrometry of hydride generation atomic.But,in process of measuring the As,Sb,Bi used atom fluorescence spectrometry,there are many factors affected the results.Through a series of experimental studies,and comprehensive analysis the various factors that may raised which concluded the samples preparation (such as sample weight,samples decomposition,media test solution,acidity choosing,effects of coexisting ions and eliminate the impact of the reagent blank),the contamination of high levels samples and instrument conditions(such as negative pressure,the carrier gas,shielding gas flow,observation height and the concentration of the reducing agent) on measuring the As,Sb,Bi used the fluorescence spectrometry of hydride generation atomic,the corresponding solution was proposed,and the more reasonable analysis conditions also was obtained.It provides a reliable guarantee for measuring the As,Sb,Bi of the geochemical samples.
