This was carried out by optimizing the fraction cut-off volume of the eluting solvent and deactivation levels of different adsorbents for column chromatography. Using a combined column (5 g aluminum oxide, deactivated with 5% H2O plus 5 g fully activated silica gel) and cutting off PCB collection, after elution with 50 mL n-hexane, led to satisfactory separation of PCBs and PAHs. The approach of this study was to decrease solvent volume and analysis time during cleanup procedure compared to the US EPA standard methods (EPA Methods 610 and 608 for PAHs and PCBs, respectively).eninfo:eu-repo/semantics/openAccessPCBPAHfractionationcolumn chromatographyArticle137679684N/AWOS:000223407600016Q4
