Electrochemical determination of 2,4-D at a mercury electrode

β-cyclodextrin functionalized graphene nano platelets for electrochemical determination of triclosan

“…a), the oxidation of triclosan occurs at about 0.70 V. The oxidation peak current is about 1.2 µA. This is an irreversible process, agreeing with those reported . When the GNP coated is applied (Fig.…”

“…Our results are comparable with those published in literature. For example, electrochemical detection of triclosan has been realized on mercury electrode , on the screen‐printed carbon electrode , on carbon nanotube , on the carbon‐nanoparticle film , on the electrode with surfactants as well as in the hydrotrope‐driven disruption of micellar encapsulates . These electrode systems showed different sensitivity and detection limit for the detection of triclosan.…”

“…In 1999, Pemberton and Hart [11] prepared a screen-printed carbon electrode to determine triclosan by cyclic voltammetry. After then, electrochemical methods have been applied frequently for the detection of triclosan [12][13][14][15][16][17][18][19][20][21]. Different electrodes and further functionalized electrodes with various materials have been utilized to develop sensitive, selective, and stable electrochemical sensors for the monitoring of triclosan.…”

Electroanalytical Methodology for the Direct Determination of 2,4-Dichlorophenoxyacetic Acid in Soil Samples Using a Graphite-Polyurethane Electrode

“…Although this herbicide easily moves though the soil, its leaching into the groundwater can be minimized due to the degradation by microorganisms and also the absorption by plants. Its primary route of degradation in the environment is by microorganisms, which increases with temperature, humidity, pH, and organic matter content [2,3]. In Brazil, the maximum acceptable concentration of 2,4-D in water is 4.0 g L −1 , according to resolution 357 of the Brazilian National Environment Council [4].…”

“…It is well known from the literature that 2,4-D exhibits poor electroactivity on most common electrode material surfaces, such as carbon, platinum, and mercury [2]. For this reason, it is crucial to develop modified electrodes for the determination and evaluation of 2,4-D.…”
