The oxygen partial pressure above supported, coordinatively unsaturated Cr , V , Mo and Mn species was measured with a ZrO cell. Within this series the pressure ranges from 10 to 10 ppm O , with the Mn /SiO systems exhibiting the lowest values of 10 and 10 . Other pertinent properties like chemiluminescence with O and catalytic activity in ethylene polymerisation are also indicated. The manganese(II) absorption masses are thus particularly suitable for removal of traces of oxygen from liquids and gases in general but especially from polymerizable olefins.
