Method for extracting organic halogen compound |
| abstract |
The present invention uses an extraction column (1) that comprises: a first column (10) including a treatment layer (100) including a silver nitrate silica gel layer (110) and a sulfuric acid silica gel layer (130); and a second column (20) that is removably linked to the first column (10), and is loaded with a capturing layer (200) that can capture organic halogen compounds. The capturing layer (200) contains capturing bodies that each include a particulate carrier containing aluminum oxide, and fine particulate silver held on the surface of the carrier. An aliphatic hydrocarbon solvent is fed to the treatment layer (100) to which an organic halogen compound-containing solution has been added. The aliphatic hydrocarbon solvent is passed through the treatment layer (100) and the capturing layer (200) in this order. An extraction solvent of organic halogen compounds is fed to the capturing layer (200) from a lower side of the second column (200). The extraction solvent that has been passed through the capturing layer (200) is obtained through a branch path (22). |
