Purifying agent for oily liquid containing polybiphenyl chloride |
| abstract |
A column 1 for removing an interfering substance to an analysis of polychlorinated biphenyls contained in an oily liquid such as an electric insulating oil from the oily liquid, includes a first column 10 packed with a multilayer silica gel 13 in which an upper layer 14 of a sulfuric acid silica gel is stacked on a lower layer 15 of a nitrate silica gel and a second column 20 connected to the lower layer 15 side of the column 10 and packed with an alumina layer 23. The nitrate silica gel of the lower layer 15 is produced by treating an activated silica gel with a mixed aqueous solution of copper nitrate and silver nitrate, wherein the ratio by mole of the copper element to the silver element (the copper element: the silver element) is preferably from 1 : 0.5 to 2.0. |
