| Abstract: | In this experiment,benzene was used to extract nitrobenzene from milk,and detected with vapor phase chromatography.Chromatographic condition was as follows: chromatographic column was DB-23 column,split ratio was 40:1,flow rate was 2.0 mL·min-1,injection mouth temperature was 230 ℃,detector temperature was 250 ℃,from 100 to 220 ℃,temperature programming by 10 ℃·min-1.Carrier gas was hydrogen.The result indicates that the method can be used to detect nitrobenzene in milk exactly. |
