Effects of Electrodeposition Conditions and Protocol on the Properties of Iridium Oxide pH Sensor Electrodes
The properties of iridium oxide pH sensors produced by electrochemically induced deposition on gold electrodes were examined as a function of the composition of the deposition solution, as well as the electrochemical deposition protocol. The composition of the Ir IV deposition solutions, which included oxalate or ethylene diamine tetraacetic acid complexing agent or no complexing agent, had no ...
متن کاملA pH Electrode Based on Melt-Oxidized Iridium Oxide
Fabrication and characterization of a novel potentiometric pH electrode based on melt-oxidized iridium oxide film is presented. The oxide film produced in a lithium carbonate melt has the composition of LixIrOy•nH2O, and shows high chemical stability. The electrode based on this oxide film exhibits very promising pH sensing performance, with an ideal Nernstian response in the tested pH range of...

متن کاملOptical pH Sensor Based on Quinizarin for Alkaline pH Regions
The development of an optical pH sensor based on immobilization of quinizarin (1,4-dihydroxyanthraquinone) on a triacetylcellulose membrane was described. The resulting membrane exhibited fast color change from yellow to violet, while changing the pH in alkaline region. The immobilized quinizarin showed a broader dynamic range from (pH 9.4-11.4) with respect to free form (pH 8.8-10.4). The sens...
متن کاملEfficient Determination of Butylated Hydroxyanisole Using an Electrochemical Sensor Based on Cobalt Oxide Nanoparticles Modified Electrode
A simple and reliable electrochemical sensor based on cobalt oxide nanoparticles modified glassy carbon electrode (GCE/CoOxNPs) for determination of butylated hydroxyanisole is presented here. The nanoparticles were fabricated by electrodepositing method. The modified electrode shows excellent catalytic activity toward butylated hydroxyanisole oxidation in pH 12.0 phosphate buffer solution (PBS...
