Ti/TiO₂ indicator electrodes formed by plasma electrolytic oxidation for potentiometric analysis

Review of Chloride Ion Detection Technology in Water

“…Many scholars have studied sensitive film materials on electrodes, such as silver thiocyanate, tripod fluorides, graphene-based selective film electrodes, metal oxide sensors, etc. [50][51][52][53][54]. Jiang et al [55] disclosed a photochemical method for the detection of Cl − concentration in water by using a three-electrode system, which was mainly constructed by a bismuth-based compound thin-film working electrode, auxiliary electrode, and reference electrode.…”

Synthesis of a Novel Sensor Electrode Based on Bromothymol Blue as an Indicator Electrode in Potentiometric Acid-Base Titration in Aqueous Solution

“…Different types of electrode have been used as acid-base indicator electrodes. Of those, the most frequently used are the titanium, hydrogen-palladium and other electrodes [9][10][11][12].…”

“…To study the thermal stability of the sensor, calibration graphs were constructed at different test solution temperatures 15, 25, 35 and 45 C. According to Figure 6. The sensor would be used for pH measurements in the range from (2)(3)(4)(5)(6)(7)(8)(9)(10)(11). At lower temperatures, like 283 K, the slope of the sensor was about 34.12 mV/decade.…”

A Spin Coating of Thymol Blue Indicator on F-SnO2 Glass to fabricate a Novel Sensor Electrode in Potentiometric Acid-Base Titration

“…The Thymol blue sensor response was evaluated at different temperatures, Figure 4. At lower temperatures, like 288K, the slope of the sensor was about 33.54mV/decade and the sensor would be used for pH measurements in the range from (2)(3)(4)(5)(6)(7)(8)(9)(10)(11). However, when the temperature of the test solutions was adjusted to 298K, the slope significantly increased to 53.11mV/decade.…”

“…Titrimetric procedures based on a detection of the endpoint, i.e., the point at which volumetric titration is completed, are successfully employed over a wide range of concentrations and are popular because of their simplicity, speed, accuracy and good reproducibility [9]. Recently, many studies developed some types of electrodes in potentiometric acid base titration [10][11][12][13]. Thymol blue (thymolsulphonephthalein) is used as a pH indicator.…”
