Abstract

In this study, a rapid and selective solid-phase extraction (SPE) by stacking two cartridges, octadecyl bonded silica (C18) and polymeric sorbents (LiChrolut EN or Isolute ENV+) for the determination of organic compounds (polycyclic aromatic hydrocarbons (PAHs), chlorpyrifos, sterols, phenol and pentachlorophenol) in water was developed. The non polar and moderately polar compounds were trapped in the C18 sorbent while the more polar compounds were trapped in the polymeric sorbent. Using C 18, acceptable recoveries of non polar compounds, PAHs (84.4-101.5%) and chlorpyrifos (99.4 %) were obtained in first elution with n-hexane while moderately polar compounds, sterols (89.7-98.6%) were recovered in the second elution using stronger eluting solvent (DCM). Factors affecting the recoveries of the target analytes such as addition of organic modifier to the sample, pH of sample and types of eluting solvent were considered. The presence of10% (v/v) methanol was most appropriate for the enrichment of PAHs (3-6 rings), chlorpyrifos and sterols on C18. Acceptable recoveries (94.8-100.8%) of the more polar compounds (phenol and pentachlorophenol) from polymeric sorbents were achieved using DCM as the eluting solvent. The developed approach is able to shorten analysis time for the analysis organic compounds over a wide polarity range in water.
