This research deals with the corrosion inhibition of mild steel in a highly corrosive aqueous HCl medium concentration 0.5 M, using three different inhibitors: furan-2-carboxylic acid (
Aflatoxin B1 (AFB1) is the most toxic contaminant, causes carcinogenic, and immune effects. There an immense need to develop inexpensive, reliable biosensors for AFB1. The electrochemical aptasensor detection of aflatoxin has received much attention due their trustworthy procedure. In this work, we have designed by using methylene blue (MB) as a signalling fragment polythiophene-3-carboxylic acid (PT3C) signal-enlarging platform. was first screened onto screen printed carbon electrode (SPCE)...
Today, organic wastes (paints, pigments, etc.) are considered to be a major concern for the pollution of aqueous environments. Therefore, it is essential find new methods solve this problem. This research was conducted study use electrochemical processes remove pollutants (e.g., crystal violet (CV)) from solutions. The galvanostatic electrolysis CV by Ti/Pt/SnO2 anode, were in an cell with 100 mL solution using Na2SO4 and NaCl as supporting electrolyte, effect important parameters: current...
Abstract A glassy carbon electrode surface was modified with an electropolymerized film made of pyrrole and β‐cyclodextrin 1∶1, in a 0.1 M LiClO4 solution using cyclic voltammetry. The resulting (Ppy/β‐CD) exhibits interesting electrocatalytic activity toward the electrochemical oxidation neurotransmitters such as dopamine (DA) norepinephrine (NE). Well‐resolved reversible voltammograms (CVs) were obtained for these organic compounds H2SO4 solution. effect pH on voltammetric response DA NE...
Abstract In this paper, we present preliminary results for the preparation and application of a biosensor intended to detect photosynthetic inhibiting herbicides such as atrazine. Our approach is based on glassy carbon electrodes operating at open‐circuit serving immobilization enzyme polyphenol oxidase (PPO) during anodic electropolymerization polypyrrole (PPy). The trapped electrode surface electrochemical synthesis process. A biological reactor can then be realized. Once (the film...
Abstract Successful applications of different analytical procedures to determine quantitatively mercury in aqueous media can be found recent literature. Fundamentally it has made use Cold Vapour Atomic Absorption Spectrometry (CV‐AAS), X‐Ray Fluorescence or UV Spectrophotometry, Inductively Coupled Plasma Emission (ICP‐AES), Mass (ICP‐MS), which are the techniques commonly used for trace measurement heavy metal laboratory. In this paper a new and alternative methodology is reported. A...
Abstract A film of polypyrrole/γcyclodextrin (PPY/γCD) was synthesized at a gold electrode by the simple electropolymerization 1∶1 mixture γCD and pyrrole monomer in aqueous solutions. Different voltammetric behaviors were obtained between PPY/γCD PPY during electrosynthesis process. Electrochemical impedance spectroscopy (EIS) used to characterize electrical properties electropolymerized films. The films exhibit interesting such as wider potential range for electroanalytical exploration...
Abstract A simple approach for increasing the sensitivity and selectivity detection of mercury(II) species in water is presented. The technique based on two steps: (1) micro‐extraction (uptake step) by simply incubating an electropolymerized poly(3‐methylthiophene) (P3MT) modified gold electrode, at open‐circuit potential conditions, into a solution containing heavy metal 30 min (2) electrode transferred from analyte to electrochemical cell (release successive voltammetric determinations....
Abstract A solid Sonogel‐Carbon electrode was modified for the determination of Hg (II) in industrial waste water. 3‐Methylthiophene (3MT), pyrrol, poly‐3‐methylthiophene (P3MT), polypyrrol, and C18 were used chemical modification. The obtained composite electrodes tested their response to Hg(II); best results observed 3MT monomer modification with a detection limit 10−2 mg · l−1 3 weeks lifetime use. linear relationship between anodic peak height concentration inside range 0.07–0.42...
