T he determination of arsenic in feed by the atomic fluorescence spectrometry was investigated.Optimum working conditions of the instrument were studied,including flow rate of carrier gas,concentration of potassium tetrahydrobo-rate solution and acidity of sample solution.Under the optimum condition,the detection limit of arsenic was 0.04 ng/mL,and recovery was in the range of 95.8%~99.7%.The method could apply in the determination of arsenic in feed successfully.
