A Silver/Silver Sulfide Selective Micro-Electrode Prepared by Chemical Treatment of Silver Wire
نویسنده
چکیده
The preparation conditions and the performance of a small size Ag/Ag2S selective electrode are described. The analytical behaviour of this electrode, made by chemical treatment of a silver wire, is described in terms of potential concentration curves, standard potential, lifetime and electrode selectivity. A series of electrodes have been prepared and investigated. Their response and selectivity to Ag+ and S2are measured and compared with those of a commercial Orion silverlsulfide electrode. Several titrations were performed to evaluate the performances of the electrode. The investigated electrode can be used, as a good substitute for the commercial silverlsulfide electrode, in a wide variety of practical analytical systems.

Preparation and Characterization of Home-Made Silver Sulphide Based Chloride Selective Electrode
Introduction A number of works on cationic sensors have been reported in literatures [1] but less attention has been given towards the development of anionic sensors though there is a need for analysis of varieties of anions in different environmental, biomedical, industrial as well as chemical samples[2-3]. Anion sensors are simple, low cost, convenient, portable and provide quick response tow...

Powders of silver sulfide have been synthesized by chemical bath deposition from aqueous solutions of silver nitrate and sodium sulfide in the presence of sodium citrate or EDTA-H2Na2. Colloid solutions have been prepared by a chemical condensation method from the same aqueous solutions. Synthesized silver sulfide nanopowders have a monoclinic (space group P21/c) acanthite-type structure but th...

Preparation and performance of a cost effective silver sulfide based bromide selective membrane is described. A solid contact between membrane and body of the electrode was examined as an ion-selective electrode by determining S 2and Br ions by direct potentiometry. A linear response to bromide ion from 2 x 10 -5 to 10 -1 M with a slope of 57.3 mV per decade [Br ] is observed. The membrane has ...

Developing simple, sensitive and selective sensing systems for dopamine is important due to its biological significance. In this work, a silver nanoparticles-modified carbon paste electrode (AgNPs-CPE) has been constructed and used to detect of dopamine (DA) in the simultaneous presence of ascorbic acid (AA) and uric acid (UA) at neutral pH 7.0 by cyclic voltammetry. The modified electrode show...
