A disk-type solid-phase extraction method for simultaneous extraction of a wide range of semi-volatile organic compounds in water samples was developed. The developed method could extract 186 out of 202 model compounds from spiked environmental samples (0.1 μg/L) with 94% average recovery (50 – 111%). Compared with the previous cartridge-type method, the extraction time was reduced to approximately 1/6. Applying the combination of the developed method and the database system to environmental samples for non-target analyses, 39 micro-pollutants with a wide range of physicochemical properties were determined.
