[A method for determination of volatile organic compounds in drinking water by purge and trap in combination with gas chromatograph/mass spectrometry].
OBJECTIVE
To establish a method of purge and trap in combination with gas chromatograph/mass spectrometry(P and T-GC/MS) for the rapid determination of minimum multi-mixture of volatile organic compounds (VOCs) in drinking water simultaneously.


METHODS
The experimental conditions of P and T, such as desorption temperature, desorption time, the type of the trap and the analytical conditions of GC were optimized. 54 VOCs in drinking water were determined by P and T-GC/MS.


RESULTS
The method enjoyed a wide linear range and good precision, the method detection limit(MDL) was 0.01 - 0.5 microg/L, the average recoveries of the method was 90% - 110% and the relative standard deviation (RSD) was 1.24%-7.79%.


CONCLUSIONS
The results showed that the method was accurate and high sensitivity and might be good for application and suitable for trace analysis of VOCs in drinking water.
