Abstract

The binding constants, K_DOC, of selected polycyclic aromatic hydrocarbons (PAHs)—phenanthrene, anthracene, fluoranthene, and pyrene—to dissolved humic substances (DHS) were determined by complexation–flocculation combined with microwave-assisted headspace solid-phase microextraction (CF-MA-HS-SPME). The results obtained are comparable with K_DOC data reported in the literature. No disruption of the PAH to DHS binding equilibrium was observed during the complexation–flocculation process. The present study, which is the first to determine K_DOC by CF-MA-HS-SPME, provides an alternative approach to determine the K_DOC of PAHs. CF-MA-HS-SPME provides some advantages over other methods, such as no limitation of fluorescent compounds, greater determination speed, and the capability of measuring various compounds simultaneously.
