Volatile Organic Compounds Determination in Drinking Water by GC/MS Spectrometry with Puffing and Trapping Samples

Objectives To establish a method for the determination of 12 kinds of volatile organic compounds (VOCs) in drinking water simultaneously by gas chromatography-mass spectrometry with puffing and trapping samples (P&T-GC/MS).

Methods Twelve kinds of volatile organic compounds (VOCs) in drinking water based on the Standards for Drinking Water Quality (GB 5749-2006) were separated by HP-VOC capillary column with temperature programming, detected by gas chromatography-mass spectrometry with puffing and trapping samples, and quantified by using external standards.

Results The linear range for VOCs was 0.4 μg/L~100.0 μg/L (r=0.998~0.999); the detection limits were 0.011 μg/L~0.196 μg/L; the relative standard deviation was 2.37%~6.29% (n = 11); and the spiked recovery were 78.0%~119.5%.

Conclusions This method were suitable for simultaneous determination of 12 kinds of volatile organic compounds in drinking water based on the regulation in the Standards for Drinking Water Quality.
