A New Chemometric Strategy in Electrochemical Method Optimization for the Quantification of Cefdinir in Tablets, Effervescent Tablets and Suspension Samples

Abstract: A new voltammetric method, based on the use of single‐use pencil graphite electrode, was developed for the quantitative determination of cefdinir by square wave voltammetry. Chemometric optimization strategy was used to select the suitable values for three experimental parameters (pH of the supporting electrolyte, frequency and square wave amplitude) by applying a 33 full factorial design model. The optimal voltammetric conditions were found to be pH 5.0 for supporting electrolyte (Britton‐Robinson buffer), 43… Show more

“…Additionally, the fact that PGEs can be exploited over a wide range of both negative and positive potentials extends the type and number of compounds that can be analyzed. The published studies proved that unmodified PGEs can successfully perform from −1.20 V [22] to +1.40 V vs. Ag/AgCl [23].…”

“…Meanwhile, the science called chemometrics developed powerful mathematical tools suitable for the optimization of rather complex (electro)analytical procedures or other types of chemical processes. For example, in the case of the cefdinir SWV determination for a bare PGE, a chemometric strategy was employed to select the optimum values of the supporting electrolyte pH, and the frequency and amplitude of the square wave [23].…”

“…The application of electrochemical techniques in the analysis of drugs and pharmaceutical products either in biological medium has increased considerably in recent years (Table 1). [33–68] The renewed interest in electrochemical techniques can be attributed in part to more sophisticated instrumentation and increased understanding of the technique themselves. The application of different electrochemical modes in the analysis of drugs and pharmaceuticals are available for the quantification of drugs.…”
