In situ fabrication and design of a novel electrochemical sensor based on the Ag_3.84Sn₃S₈@rGO nanocomposite for competitive ultra-detection of metronidazole in human urine

Abstract

It is an indispensable demand to design an efficient technology for reducing contaminants in wastewater. Thus we have developed a novel nanocomposite catalyst by in-situ formation of non-stoichiometric Ag3.84Sn3S8 on...

Environmentally benign fabrication of superparamagnetic and photoluminescent Ce,Tb-codoped Fe3O4-gluconate nanocrystals from low-quality iron ore intended for wastewater treatment

“…The fundamentals of this test involve the dependence of the electrochemical impedance on the experimental potential range, which can be converted to the capacitance. 75,76 The capacitance and the potential are related by the following equation:1/ C 2 = (2/ A 2 eεε 0 N D ) ( E − E FBP − kT / e )where, ‘ C ’ is the space-charge capacitance, ‘ A ’ is the area of the working electrode, ‘ e ’ corresponds to the electronic charge, ‘ ε ’ and ‘ε 0 ’ are the dielectric constants of the working electrode and the free space, respectively, ‘ N D ’ is the charge carrier density, ‘ E ’ is the working potential [against the standard calomel electrode (SCE)], ‘ E FBP ’ is the flat band potential (Fermi level), ‘ k ’ is the Boltzmann's constant and ‘ T ’ is the temperature. Here, we have performed this experiment at 1000 Hz.…”
