“…If the reduction of two same groups with different environments and different location and of course different relative energies is thought to be possible at the same potential, and this splitting could be considered as two different peaks than it is plausible to propose the reduction of two etheric or more possibly two carbonyl oxygen to corresponding alcohols as reduction mechanism. Otherwise, there is only one group possible to be reduced with participation of four electrons and four protons and this mechanism was shown in Scheme 2 with support of similar mechanisms in the literature (Jain et al, 2007(Jain et al, , 2008 although it is not met our theoretical investigations.…”

Electrochemical behavior of cefditoren pivoxil (CTP) was studied via experimental electrochemical methods and theoretical calculations performed at B3LYP/6-31+G(d)//AM1 level. Experimental studies were carried out based on an irreversible 4eÀ/4H+ reduction peak at ca. À0.8 V on hanging mercury drop electrode (HMDE) and irreversible 1eÀ/1H+ oxidation of CTP at ca. 0.8 V on glassy carbon electrode (GCE) versus Ag/AgCl, KCl (3.0 M) in Britton-Robinson buffer at pH 6.0 and 4.0, respectively. Tentative reduction and oxidation mechanisms were proposed based on computational and experimental results. Square-wave adsorptive stripping voltammetric methods have been developed and validated for quantification of CTP in different samples. Linear working range was established as 0.15-15.0 lM for HMDE and 1.0-50.0 lM for GCE. Limit of quantification (S/N = 10) was calculated to be (0.10 ± 0.02) lM and (0.80 ± 0.03) lM for HMDE and GCE, respectively. Methods were successfully applied to assay the drug in tablets and human serum with good recoveries between (99.2 ± 11.6) % and (102.5 ± 9.5) % having relative standard deviation less than 10%. ª 2014 Production and hosting by Elsevier B.V. on behalf of King Saud University.

“…Surfactants influence the electrochemical processes of electroactive species [50][51][52] and thus are widely used in electroanalytical chemistry to improve the sensitivity and selectivity [53][54][55][56]. Adsorption of surfactant aggregates on the electrode surface via hydrophobic interactions might significantly facilitate the electron transfer; change the redox potentials or charge transfer coefficients or diffusion coefficients by stabilizing radical ions and other reaction intermediates and also by modifying the double layer structure [50,[57][58][59] The effects on the peak currents of CLZ using two ionic surfactants such as cetyltrimethylammonium bromide (CTAB-cationic) and sodium dodecylsulfate (SDSanionic) and a non-ionic surfactant such as Triton X-100 (TX-100) as an in situ modifier were investigated.…”

A carbon ionic liquid electrode modified in situ with sodium dodecylsulfate (SDS) was developed for the determination of clozapine (CLZ). These studies revealed that the oxidation of CLZ is facilitated at an in situ surfactantmodified carbon ionic liquid electrode (ISS-CILE). After optimization of analytical conditions, the peak currents for CLZ were found to vary linearly with its concentrations in the range of 1 10 À9 -1 10 À7 mol L À1 with a slope of 2.18 mA/mmol L À1 . The LOD and LOQ of the electrode were 2.08 10 À10 mol L À1 and 6.95 10 À10 mol L À1, respectively. The proposed method was employed for the determination of CLZ in pharmaceutical formulations, blood serum and plasma samples without any pretreatment steps.
