Simultaneous Determination of Trace Antimony and Bismuth in Jilin Ginseng with Microwave Digestion Hydride Generation Atomic Fluorescence Spectrometry

摘要：

　　A robust,accurate and sensitive analytical procedure was developed for the simultaneous determination of trace Antimony and Bismuth in Jilin ginseng by hydride generation atomic fluorescence spectrometry.The parameters were studied systematically,such as acid concentration of the reaction medium,flow rate of the carrier gas and shield gas,the atomizer of height,etc.Ascorbic acid and thiourea were used as reducer or masking agents to enhance the generation efficiency of the volatile species of Sb and Bi.In the presence of thiourea and ascorbic acid,the influences of some coexisting elements on the determination of antimony and bismuth were investigated.
