| 英文摘要 | a home-made stir bar sorptive extraction (sbse) apparatus was combined to a single photon ionization time-of-flight mass spectrometer (spi-tofms) for rapid and sensitive determination of trace volatile organic compounds (vocs) in water. the home-made sbse bar, low-cost and disposable, was used for vocs extraction. a thermal desorption (td) device was designed to desorb the analytes from the sbse bar, and a high throughput interface was developed to transfer the analytes into the ionization chamber of the spi-tofms. the combination of large extraction volume of sbse bar, and the direct measurement power of spi-tofms enable a short analysis time for vocs in water with high sensitivity, for example the limits of detection (lods) were in the range of 7.4-11.1 ng l-1 for benzene, toluene, and p-xylene (btx) within 15 min. btx aqueous solutions were chosen to demonstrate the quantitative capability, the linear range was from 0.05 to 100 mu g l-1 and the correlation coefficients were better than 0.996. the proposed method was successfully applied for the analysis of vocs in urban river water. |
