Abstract:In national standards GB/T 4103.2—2012 and GB/T 4103.6—2012, different sample dissolution methods were used for the determination of arsenic and antimony in lead and lead alloys by hydride generation-atomic fluorescence spectrometry (HG-AFS). The determination procedures were complicated. The sample was dissolved with nitric acid. The sulfuric acid was added to precipitate out and remove the lead matrix. Meanwhile, the hydrolysis of antimony was avoided by heating sulfuric acid to control the solution acidity. And accordingly the simultaneous determination method of arsenic and antimony in sample by HG-AFS was established. The experimental results showed that the correlation coefficients of calibration curves of arsenic and antimony were higher than 0.9997 under the optimal working conditions. The detection limits of method were 0.0005μg/L and 0.0007μg/L for arsenic and antimony, respectively. The interference tests indicated that the coexisting elements in sample did not interfere with the determination. The experimental method was applied for the determination of arsenic and antimony in actual lead ingot sample. The found results were basically consistent with those obtained by national standard methods (GB/T 4103.2—2012, GB/T 4103.6—2012 or IREAC-ZY-PB01). The relative standard deviations (RSD, n=6) of determination results for arsenic and antimony were between 1.8% and 2.0%.
