15 volatile organic compounds (VOCs) in bottled waters, health drinks and product waters of a filtration plant were quantitated using headspace solid-phase microextraction (HS-SPME). Two fiber types, i.e., 100 μm PDMS and 65 μm PDMS/DVB were tested to determine the optimum extraction conditions over a concentration 0~80 ng/ml range of VOCs. At the absorption time of 4 min and the stirring velocity of 1200 rpm,coefficient of correlation for calibration curves of VOCs by 65 μm PDMS/DVB fiber were 0.9831~0.9993 over a concentration range of 040 ng/ml VOCs, whereas those values by 100 μm PDMS fibre were 0.9751~0.9945over a concentration range of 080 ng/ml VOCs. Thus, 65 μm PDMS/DVB fiber was used to extract VOCs from samples with different matrixes. Quantitation was achieved using standard calibration method. Most of VOCs were not detected in many samples. But chloroform and bromodichloromethane were detected from the water samples of 6 different types plant. The concentration range of chloroform detected in this study was nd~14.79 ng/ml (n=6), while that of bromodichloromethane was nd~8.74 ng/ml. In addition, dibromochloromethane of nd~2.14 ng/ml and toluene of nd~41.95 ng/ml were detected from 2-type and 3-type water samples,respectively. |
