TI  - Development of an in-line system for the analysis of 4,4'-DDT in water.
PG  - 807-19
AB  - An in-line system for trace persistent organic pollutants (POPs) in water was 
      developed by using a laboratory-made hollow fiber membrane (HFM) unit connected 
      with a high-resolution gas chromatograph-mass spectrometer (HRGC-MS). The 
      semivolatile organic compound, 4,4'-Dichlorodiphenyl trichloroethane (4,4'-DDT), 
      was chosen as a representative of a persistent organic compound. The synthetic 
      water contaminated with 4,4'-DDT was passed through the HFM unit, the extraction 
      occurred by the analyte pervaporated and permeated, then stripped into HRGC-MS. 
      Several factors were investigated for the high extraction efficiency. The best 
      performance was obtained at sample and stripping gas flow rates of 6 and 9 
      mLmin-1, respectively, and desorption temperature of 60 degrees C. At this 
      temperature, the diffusion rate was enhanced by 15 times over 25 degrees C. A 
      wide linear dynamic range was obtained, i.e., 0.10-1.0 mgL-1, with a limit of 
      detection (LOD) of 90 microgL-1. The extraction efficiency of 4,4'-DDT in real 
      water samples was in the range of 83-94%. Real water samples were analyzed and 
      0.6 microgL-1 of 4,4'-DDT was found in unregistered bottled water and 7.0 
      microgL-1 in tap water.
