Improvement of Amperometric Sensor Used for Determination of Nitrate with Polypyrrole Nanowires Modified Electrode
Polypyrrole(PPy) nanowire modified electrodes were developed by template-free electrochemical method based on graphite electrode. The modified electrode was characterized by their amperometric response towards nitrate ions. Before reduction of nitrate ions, electrochemical solid-phase extraction (EC-SPE) of nitrate in/on modified electrodes was conducted. It is found that the unusual nanowired ...
متن کاملAmperometric Sensor Used for Determination of Thiocyanate with a Silver Nanoparticles Modified Electrode
A novel electrode modified with silver nanoparticles was fabricated. It is found that the reducibility of silver nanoparticles is higher than for bulk silver by comparing a silver nanoparticles modified electrode with a silver micro-disk electrode. When SCN was added, a new oxidation peak occurred and the anodic peak current of silver nanoparticles decreased. The new anodic peak current is prop...
متن کاملA New Electrochemical Sensor for Determination of Zolpidem by Carbon Paste Electrode Modified with SnS@SnO2NP
Zolpidem is a drug that is easily attached to the GABA receptors in the brain. This property makes it very effective for tranquilizing as well as hypnagogia. According to the advantages of electrochemical analysis like high selectivity, high sensitivity, low concentration of analyte, cost-effective, portable and easy-to-use setup, they gained high amount of attention among scientists for determ...
متن کاملAlumina nanoparticles modified carbon paste electrode as a new voltammetric sensor for determination of dopamine
The present study examines a new dopamine sensor based on Alumina nanoparticles modified carbon paste electrode (Al2O3NPsCPE). Moreover, the present study focuses on the electrochemical act of the Al2O3NPsCPE for the detection of dopamine by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). There is also a focus on the specification of the prepared modified electrode by electroc...
