Voltammetric study of cefotaxime at the macroscopic and miniaturized interface between two immiscible electrolyte solutions.

ABSTRACT: The electrochemical behavior of cefotaxime (CTX⁺) was investigated at the polarized macro- and micro-interface between two immiscible electrolyte solutions (ITIES) by cyclic voltammetry and alternating current voltammetry. Miniaturization was achieved with fused silica microcapillary tubing entrapped in a polymeric casing. Scanning electron microscopy (SEM) was employed for the fabricated LLI support characterization. Voltammetric investigation of CTX⁺ at macro- and μ-ITIES allowed the determination of many physicochemical parameters, such as formal Galvani potential of the ion transfer reaction ([Formula: see text]), diffusion coefficients (D), formal free Gibbs energy of the ion transfer reaction (∆G^{'aq → org}), and water-1,2-dichloroethane partition coeff
