要約
(EN)
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.

(FR)
La présente invention concerne une colonne (1) destinée à retirer une substance qui gêne l'analyse du polychlorure de biphényle contenu dans un liquide huileux tel qu'une huile d'isolation électrique. Cette colonne comprend une première colonne (10) remplie avec un gel de silice multicouche (13) qui comporte une couche supérieure (14) comprenant un gel de silice aux sulfates et une couche inférieure (15) comprenant un gel de silice aux nitrates, et une deuxième colonne (20) reliée au côté de la couche inférieure (15) de la première colonne (10) et remplie avec une couche d'alumine (23). Le gel de silice aux nitrates de la couche inférieure (15) est obtenu en traitant un gel de silice active avec une solution aqueuse mixte contenant du nitrate de cuivre et du nitrate d'argent, le rapport molaire entre le cuivre élémentaire et l'argent élémentaire étant de préférence de 1 : 0,5 à 2,0.
