Abstract: In a standing pipe body (210), an adsorbent layer (240) filled with active magnesium silicate as an adsorbent and an alumina layer (250) positioned therebelow are arranged. A sample solution containing dioxins is applied into the pipe body (210) from the top, and an aliphatic hydrocarbon solvent is subsequently supplied into the pipe body (210) from the top. The aliphatic hydrocarbon solvent having dissolved dioxins in the sample solution passes through the adsorbent layer (240) and the alumina layer (250) in this order, and is discharged from a bottom of the pipe body (210). At this point, a dioxin group including non-ortho PCBs, PCDDs, and PCDFs is selectively trapped by the adsorbent layer (240), and mono-ortho PCBs are selectively trapped by the alumina layer (250).
