Summary: The electrochemical properties of quetiapine fumarate were studied using a multi-walled carbon nanotube modified electrode. The optimal concentration of multi-walled carbon nanotubes was determined. The oxidation process of quetiapine fumarate was found to be irreversible and controlled by adsorption. The linear ranges and detection limits for differential pulse stripping voltammetry and square-wave stripping voltammetry were determined. The methods were successfully applied for the analysis of quetiapine fumarate tablets. The groups responsible for the oxidation reaction of quetiapine fumarate were investigated using model substances.

Summary: The kinetics of formation of carbon nanotube aerogel (CNT-a) by thermocatalytic decomposition of ethanol using ferrocene and thiophene as catalyst and promoter has been studied. It was found that the irreversible dissociation of adsorbed ethanol followed by the decomposition of adsorbed ethyl group is the rate limiting step for the formation of CNT-a. Additionally, the atomic ratios of Fe/S and Fe/C were found to have profound effects on the type of carbon nanotubes present in CNT-a.

Summary: In this study, a quick, simple, and sensitive voltammetric method is developed using chemically modified electrodes to determine paracetamol (PCT) in complex matrices. The carbon paste electrode is modified with stevensite monoclinic clay mineral (Stv-CPE) using cyclic voltammetry, differential pulse voltammetry, and electrochemical impedance spectroscopy. The method has a detection limit of 0.2 μM and a quantitation limit of 0.5 μM under favorable conditions, with a linear working concentration range of 0.6-100 μM for PCT. The proposed method is applied to quantify the PCT content in reference tablet formulations and biological samples for validation.

Summary: A modification-free, paper electrode based on vacuum-filtered SWCNT thin film was developed for electrochemical detection of BPA. The electrode showed a linear response in the concentration range of 0.5-10 μM and 25-100 μM, with an experimental LOD of 1.0 μM (S/N=3). Interference study and good recovery percentage (93-105%) in real water samples demonstrated the selectivity of the method. The sensor has potential for developing a simple, low-cost, portable, and paper-based BPA monitoring system.
