| Abstract: | the determination of the chloropicrin remains in five wheat samples by gas chromatography method was discussed in this paper.Those results showed that the method by using acid circumfluence and capillary chromatogram detection was sensitive.There was a significant correlation between the chromatogram area and Chloropicrin concentration when the range of chloropicrin concentration was from 1 g/mL to 20 g/mL,and the correlation coefficient of standard analysis curve was 0.998 4.The extraction rate of chloropicrin was 95.38% and standard deviation was 3.42%. |
