“…3A) [33]. Moreover, in literature it is suggested that it is a reductive cleavage of the carbon-chlorine bond [34,35]; a further mechanistic discussion can be found in literature [35]. Optimized parameters ended up being the following: potential of deposition (for 60 s) of −0.20 V, electrochemical window from −0.20 to −0.50 V, potential step of 4 mV, potential pulse of 0.12 V with a scan rate of 4 mV s −1 (i.e.…”

The determination of 1-chloro-2,4-dinitrobenzene (CDNB) was used as a proof-of-concept to a simple analytical practical configuration applying magnetic molecularly imprinted particles (mag-MIPs). Mag-MIPs were captured from an emulsion by a home-made magneto-sensor (where a small magnet was entrapped by a graphite-epoxy composite) and then, this sensor, was transferred to the solution containing the analyte, where, after binding to the mag-MIPs, the analyte was directly analysed using differential pulse voltammetry (DPV) since the magneto-sensor acted as the working electrode. After optimization, a detection limit of 6.0 μmol L with a RSD of 2.7% was achieved along with suitable recoveries and selectivity. This methodology offers a different approach for electroanalytical methodologies using mag-MIPs.

“…32 On the other hand, in cyclic voltammetric experiments, the equations for the surface concentration are more involved in view of its dependence on the scan rate. 33 In the case of ultramicroelectrodes, 34 the surface concentrations depend upon the geometry of the electrodes as well as the mechanism under consideration. Hence it follows that explicit equations for surface concentrations pertaining to electrochemical experiments are essential to comprehend reaction mechanism.…”

The transient current-potential response of the enzyme-catalyzed oxygen reduction reaction in biofuel cells is analyzed. The onedimensional nonlinear reaction-diffusion equation is solved analytically using the homotopy method for deriving the substrate concentrations and current densities pertaining to chronoamperometric response. The time required to obtain the steady state has been obtained and the influence of film thickness, diffusion coefficients, and enzyme characteristics has been deciphered. The equations are shown to be valid for experimental data on mediated electron transfer reactions of redox polymers containing osmium complexes. The substrate concentrations and current densities for supported, gas-diffusion and flow through electrodes are also reported.

“…Reductive cleavage of carbon-halogen bonds is probably the most exhaustively studied DET process and electrochemical methods in particular have emerged as highly sensitive probes of the reaction mechanism. Numerous reports examining and/or applying the reductive cleavage of carbon-halogen bonds appeared in 2005, [62][63][64][65][66][67][68] two of which are selected for illustration.…”
