| A method was established to determined turpentine in water by headspace gas chromatography.The test conditions such as vial temperature,vial equilibration time,dosage of NaCl,sampling volume were optimized.The method shows good linearity from 0.200 mg/L to 4.00 mg/L; the method detection limits were found to be 0.037 mg/L.Two mass concentration levels of the blank recoveries ranged from 89.3% to 108%,and the relative standard deviations of turpentine were 5.8% and 4.8% respectively． |
