摘　　要：本文以四通道原子荧光光度计为基础,详细研究点火炉丝的温度、泵速、溶液的酸度、硼氢化钾浓度、硫脲浓度及还原时间、载气及屏蔽气流量等实验参数对As、Sb、Bi、Hg等元素荧光强度的影响,分析得出原子荧光多元素同测时各参数的设置原则。In this paper,based on the four-channel non-dispersive atomic fluorescence spectrometer, the inlfuence of the lfuorescence signal intensity of the elements such as arsenic,antimony,bismuth and mercury of experimental conditions that the temperature of the heating wire,pump speed,solution acidity, potassium borohydride concentration,concentration of thiourea and restore time,carrier gas and shielding gas lfow were detailed studied,Through analysis it is concluded that the setting principle of each parameter simultaneous determination of multielement by the atomic fluorescence.
