Abstract:A modified polar organic compounds integrated sampling technique was calibrated to monitor perfluorinated chemicals (PFCs) in water. Uptake kinetics of PFCs and the effect of flow velocities on the sampling rates were investigated. The results showed that, in 10d, the enrichment of PFCs under different flow velocities showed a linear relationship. The sampling rates of PFCs decreased with the flow velocity (0.085~0.0018m/s), but no obvious effect was showed on perfluoroundecate (PFuDA). The established POCIS sampling technique was applied to the surface water in Nanjing City and compared with the conventional active monitoring technique. The calculated concentration by POCIS sampling technique and the measured concentration by the twice active monitoring method were in basic agreement.
