This study investigated the oxidation of ascorbic acid (Vitamin C) using a platinum nanoparticle electrode coated with an iodine monolayer, called a modified electrode. The electrode were grown using the cyclic voltammetry technique and the electrochemical measurements were taken using the cyclic voltammetry and chronoamperometric technique. In the case of platinum nanoparticle electrode modifi...

the glucose oxidase (gox) electrochemical sensors were used to detect a little amount of glucose. in this paper, the pure platinum plate (length of 5 cm and a width of 3 mm), the ag/agcl electrode and platinum electrode (diameter of 1 mm) were applied as a working electrode (w.e), reference electrode and auxiliary electrode sequential. factors measured, glucose concentration and ph is phosphate...

the microbial fuel cells (mfcs) are a kind of systems through which the anaerobic bacteriaalong with the oxidation of simple or complicated organic matter in the wastewater can generate the electricpower. this is a modern approach used in generation of the clean and renewable energy. in this research, two pilot laboratories of double-chamber microbial fuel cells were made. one of them contained...

in the present study, a new gas diffusion electrode (gde) (based on pt/nafion membrane) is fabricated. the electrochemical results show that the new gde has the highest electrochemical activity toward the oxygen reduction reaction (orr) among the three electrodes. the sem and xrd findings show that a platinum layer can be attached to nafion membrane closely and firmly with a strong peak corresp...

A tantalum deposited platinum electrode that offers an enhanced catalytic four-electron reduction of oxygen over the bare platinum electrode in acidic solution is explored.

a new al(iii) selective membrane based on 5-bromo(salicylidene-2-amino thiophenol) as a neutral carrier in a poly(vinyl chloride) (pvc) matrix is coated on platinum wire to determine trace amounts of al(iii) ion in various samples. the sensor exhibits a good response for al(iii) ion over a wide concentration range of 5.20 × 10-7 to 1.00 × 10-2 m  with nernstian slope of 19.64 ± 0.15 mv decade-1...
