Abstract: Trace arsenic in stainless steel samples was determined by hydride generation atomic fluorescence spectrometry.On-Guard H column was used to remove heavy metals in digestion solution,avoiding the interference of coexisting metal elements and a large number of matrix element Fe during the determining process,and on-Guard H column had no obvious interference to the determination.Results showed that the detection limit was 0.02μg/L,the results were consistent with the theoretical value by this method.The method has advantages of simple operation,greatly improving the sensitivity and accuracy for determination of trace arsenic in stainless steel.
