| Abstract: | To establish a simple and fast high performance method to determine trace antimony in packaging materials for food,samples were done with 4% acetic acid,and trace antimony in packaging materials for food was determined by Atomic fluorescence spectrometry(AFS).The results showed that the linear range of this method was 0～20 μg/L,regression formula was y = 87.284 C-17.440,r = 0.999 9.The detection limit of this method was 0.028 4 μg/L,RSD was 0.86%～4.04%,and the recovery was at the range of 91.5% ～ 98.5%.It conclusdes the described method is simple,fast and sensitive. |
