| Abstract: | Turpentine in water was detected by gas chromatography method,which separated with type of DB-5 column,detected by FID detector.Turpentine concentration was linear with the peak area in the range of 1.00-25.0 mg/L.The recoveries of turpentine were 86.3%-91.3%,and the RSD of determination results was 8.7%(n=6).This method could meet the requirement of GB 3838-2002. |
