摘要：

Polyvinylidenefluoride (fluorocarbon polymer sorbent) with surface area 8.4 m(2) g(-1) and particle size 15-30 mu m was used for on-line SPE-HPLC determination of naphthalene, biphenyl, acenaphthene, anthracene and pyrene in natural water. Desorption eluent flow rates were varied from 0.50 to 1.75 ml min(-1) and the volume of analyte-containing eluent stream zone was 0.10-0.11 ml, while empty preconcentration column volume is 0.10 ml. Detection limits of SPE-HPLC method were established: 5 ng 1(-1) (biphenyl), 7 ng 1(-1) (anthracene), 8 ng 1(-1) (acenaphthene), 30 ng 1(-1) (pyrene), 40 ng 1(-1) (naphthalene), using UV spectrophotometric detection. Several samples of natural and potable water were spiked with mixture of PAHs, thus validating the proposed technique. (c) 2005 Elsevier B.V. All rights reserved.
