| 摘要 |
<p>The pH electrode of the present invention has a pH-sensitive region on an electrically conductive support, said pH-sensitive region comprising particles of a Group VA or Group VIII metal, in particular antimony, incorporated in or applied to a polymer substrate having a resistivity of 10 to 100 Kohms/square. The pH electrode is prepared by formation of a pH-sensitive region on an electrically conductive support by applying thereto a polymer substrate, having a resistivity of 10 to 100 Kohms/square, said polymer substrate comprising particles of a Group VA or Group VIII metal, in particular antimony, incorporated therein or applied thereto either before or after application of said polymer substrate to said support.</p> |
