نویسندگان

چکیده

Owing to the unique electronic properties, high electrical conductivity, and adsorption capacity of graphitic mesoporous carbon (GMC), a simple strategy was developed alter surface glassy electrodes with thin layer GMC. These modified were applied detect bisphenol A (BPA) in wastewater samples due strong attraction between GMC-modified BPA. Electrochemical BPA sensing processes evaluated using different electrochemical techniques, such as differential pulse voltammetry cyclic voltammetry. For all experiments, distinguished anodic peak at ~ 0.55 V observed, which attributed enhanced oxidation on electrode. In addition, influence scan rate electrolyte pH studied detail. The sensor exhibited reliable quantification wide range concentrations (i.e., 20 – 300 μM) 5.5 8.9) sensitivity 2.93 μA μM−1 cm−2 detection limit 59 nM. Finally, pre-determined parameters for secondary-treated sewage. results showed that recovery 98.13 100.36 %. summary, satisfactory reproducibility accurate even complex matrices,

Electrochemical Sensor for Determination of Fenitrothion at Multi-wall Carbon Nanotubes Modified Glassy Carbon Electrode

A sensor, based on multi-wall carbon nanotubes modified glassy carbon electrode (MWCNT/GCE), was developed for determination of fenitrothion. Determining the surface area of MWCNT/GCE showed that this surface is three times more active than that of a glassy carbon electrode. The experimental parameters, such as the amount of MWCNTs, pH of the fenitrothion solution, preconcentration potential an...

A fluorescent sensor for selective detection of cyanide using mesoporous graphitic carbon(IV) nitride.

A turn-on fluorescence sensor, Cu(2+)-c-mpg-C(3)N(4), was developed for detection of CN(-) in aqueous solution by simply mixing cubic mesoporous graphitic carbon nitride (c-mpg-C(3)N(4)) and aqueous solution of Cu(NO(3))(2). The highly sensitive detection of CN(-) with a detection limit of 80 nM is not only possible in aqueous solution but also in human blood serum.
