In this study, the determination of cyanide in Baijiu by AA3 continuous flow analyzer was explored. Through technical optimization, within the range of 0 to 200 μg/L, the correlation coefficient R~2 was 0.9999, the detection limit was 2.1 μg/L and the quantification limit was 6.2 μg/L, and the recovery rate of samples was 85.96 % to 101.81 %. The use of this method could effectively reduce the interference of liquor matrix and improve the determination accuracy and sensitivity. Besides, this method was simp...
