영문 초록

The sol-gel method was used to prepare binary metal oxide (IrO2-RuO2) pH sensor. The electrodes that mole percent compositions (mol%) of IrO2 and RuO2 were 70:30 and 30:70 were selected. The characterizations of Nernstian response over pH range, response rate, interference on alkaline metals and reproducibility were investigated. Also the electroanalytical properties of these electrodes were evaluated in comparison with a commercial glass pH electrode. The composition of IrO2:RuO2 70:30 mol% was chosen as better electrode formulation. The electrode was not susceptible to the action of interfering ions such as Li+, Na+ and K+.
