The electrochemical processes of copper in the presence of triton X‐100

Abstract

In this work, the redox processes of copper ions were studied by electrochemical methods in NaCl and NaC10, solutions in the absence or in the presence of nonionic surfactant Triton X-100 (T-X-100). The enhancement of the anodic peak current of copper in the presence of T-X-100 in sodium chloride solutions was observed depending on the concentrations of T-X-100 and copper (11) ions. This is the consequence of destabilization of the otherwise stabile CuCly complex in chloride solutions by the presence of T-X-100. The process involves disproportionation of formed copper (I) species to copper (0) and copper (11).

Carbon Paste Electrode Based on Surface Activation for Trace Adriamycin Determination by a Preconcentration and Voltammetric Method

“…Surfactant solutions are widely used in electrochemistry for various purposes, [13][14][15] such as solubilization, an enhancement effect on the peak current, to change the redox potential, and to alter the diffusion coefficient etc.…”

Electrochemical Determination of Ciprofloxacin Based on the Enhancement Effect of Sodium Dodecyl Benzene Sulfonate

“…Finally, surfactant heavily influences the electrochemical process of electroactive species. [13][14][15][16][17] To date, surfactant was widely used in electroanalytical chemistry to improve the sensitivity and selectivity. In pH 4.0 phosphate buffer, ciprofloxacin yields an oxidation peak at the carbon paste electrode (CPE) after accumulation.…”

Effects of Surfactants on the Electroreduction of Dioxygen at an Acetylene Black Electrode

“…Surfactants with an amphiphilic character can change the electrical properties of the electrode/solution interface and the nature of the electrochemical process. 9 For example, Rusling 10 has successfully used surfactant microstructures to catalyze the electrochemical dehalogenation of organic halides. Kaifer and colleagues 11,12 reported significant changes in the redox potential and peak current of methylviologen in a sodium dodecyl sulfate (SDS) micellar solution.…”

“…Kaifer and colleagues 11,12 reported significant changes in the redox potential and peak current of methylviologen in a sodium dodecyl sulfate (SDS) micellar solution. Other often used surfactants were cetyltrimethylammonium bromide (CTAB), [13][14][15] Triton X-100 9 and tetradecyltrimethylammonium bromide (TDTAB). 16 Most of these reports were based on dissolving the surfactants in an electrolyte to form a micellar solution for enhancing the electrochemical responses.…”
