[Determination of arsenic in animal liver by atomic fluorescence spectrometry].

An atomic fluorescence spectrometry for the determination of micro arsenic in animal liver was developed with high sensitivity and fine accuracy. Under the selected experimental conditions, there was a linear relationship between the fluorescence intensity and arsenic concentration in the range of 0-160 ng.mL-1 with correlation coefficient of 0.9996. The limit of detection was 0.4 ng.mL-1, and the recovery was 94.2%-98.5%.
