Copper (Cu) is a toxic pollutant and its presence in wastewater, even at low concentrations, can have significant environmental impact. In this work, method for the determination of Cu was developed using voltammetric technique involving platinum electrode citrate medium. ppb level determined by both chronoamperometry (CA) anodic linear scanning voltammetry (ALSV), results were compared to thos...

In this study, poly(N-Isopropylacrylamide) (PNIPAM), poly(acrylamide) (PAAM), poly(acrylic acid) (PAAc), and poly(methacrylic (PMAc) polymers are synthesized by radical polymerization method. The chemical composition surface morphology of the PMAc polymer examined micro-Raman spectroscopy scanning electron microscopy (SEM). electrochemical measurements cyclic voltammetry (CV), chronoamperometry...

A fundamental electrochemical measurement system for an sensor was built using a microcomputer control. It is crucial that the results can be used both qualitative and quantitative analysis. These data are estimated by cyclovoltammetry (CV) chronoamperometry (CA) measurements, which major methods in engineering field. The CV function has already been our previous study its functionality confirm...

Electrochemical deposition of rhenium-iron alloy from water-in-salt electrolytes containing a super-high concentration lithium chloride is investigated. Different techniques, including cyclic voltammetry, chronoamperometry, X-ray fluorescence, scanning electron microscope, X-Ray diffraction, and electrical measurements at cryogenic temperature are used to characterize the electrochemical system...

CO2 conversion into high-value-added products is becoming increasingly attractive to find substitutes for fossil-based ones and tackle the environmental crisis. Herein, a noble, simple, reproducible, scalable Cu2O-SnO2 photo-electrocatalyst was synthesized characterized. Coupling cuprous oxide with tin allowed protecting unstable Cu+1 species from photo-corrosion. Evidence of SnO2 stabilization...

The recently introduced diffusion indicator (Haonan et al, J. Electroanal. Chem., 2019, 855, 113602) is generalised to characterise local mass transport fluxes a non-uniformly accessible electrode probe both qualitatively and quantitatively the nature of different parts an surface at times following electrochemical perturbation. approach illustrated in respect truncated sphere on plane surface....

In this study, the effects of flow field types on electrochemical properties polymer electrolyte membrane fuel cells (PEMFCs) humidified with NaCl solution are systematically investigated. The parallel and serpentine were used to investigate PEMFCs. Long-term stability was evaluated for 20 h using chronoamperometry. Fuel both fields showed a decrease in performance because solution. Interesting...

The fabrication of acid functionalized multi-walled carbon nanotube (fMWCNT) combined apple tissue based amperometric biosensor through a cross-linking agent-free approach has been presented for the phenol detection in this study. Apple entrapped fMWCNT-glassy paste composite was employed as natural polyphenol oxidase source enzymatic oxidation and consumption dissolved oxygen monitored via chr...
