Abstract
Polyvinylidenefluoride (fluorocarbon polymer sorbent) with surface area 8.4 m2 gâ1 and particle size 15-30 μm 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 minâ1 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 lâ1 (biphenyl), 7 ng lâ1 (anthracene), 8 ng lâ1 (acenaphthene), 30 ng lâ1 (pyrene), 40 ng lâ1 (naphthalene), using UV spectrophotometric detection. Several samples of natural and potable water were spiked with mixture of PAHs, thus validating the proposed technique.
