Abstract: Nanosized metal oxides were recommended as pH-sensitive materials to fabricate solid pHsensors with screen printable technique. The metal oxide electrodes studied in this paper showed a better selectivity to hydrogen ions with the presence of alkali ions. Particularly, the outstanding advantage of these electrodes was that these electrodes were available to measure the pHof the highly corrosive system containing HF.

Key words: Solid pH electrode, Nanosized material, Metal oxide, Screen printed technique
