Abstract
A robust, accurate and sensitive analytical procedure was developed for the simultaneous determination of trace arsenic and antimony in fomes officinalis ames 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, potassium iodide and thiourea were used as reducer or masking agents to enhance the generation efficiency of the volatile species of As and Sb. In the presence of thiourea, potassium iodide and ascorbic acid, the influences of some coexisting elements on the determination of arsenic and antimony were investigated.
