A computational simulation of electromembrane extraction based on Poisson-Nernst-Planck equations

Roshanak Dolatabadi et al.

Summary: The study focuses on the ion transport mechanism in electromembrane extraction (EME) and uses a 2D numerical simulation to analyze mass transfer behavior and analyte recovery. Factors such as initial analyte concentration, SLM thickness, applied potential, diffusion coefficient, and reservoir pH are considered as process variables. The model predicts that analyte diffusivity, distribution coefficient, and protonation levels in the solutions play key roles in EME.

Chitosan biofilms: Insights for the selective electromembrane extraction of fluoroquinolones from biological samples

Cristina Roman-Hidalgo et al.

Summary: A selective electromembrane extraction method using a chitosan biofilm was proposed for the extraction of antibiotic fluoroquinolones in veterinarian use. The interaction mechanism between the target drugs and the biopolymer was deeply studied using the Quantum Theory of Atoms in Molecules. The results showed that the interaction was stabilized by hydrogen bonds, leading to high extraction efficiency and good repeatability.

Novel graphene-nanoclay hybrid electrodes for electrochemical determination of theophylline

Laxmi S. Killedar et al.

Summary: Electro-analytical methods focus on the interaction between electricity and chemistry to calculate quantities of electricity, such as current, potential, and charges, and their relationship with chemical properties. In this study, an electrode was prepared by drop casting graphene oxide-nanoclay mixture on the glassy carbon electrode surface for the quantification of a drug called theophylline. The electrochemical analysis showed that the modified electrode significantly enhanced the oxidation of theophylline and had good detection and recovery values.
