Differential Pulse Voltammetric Determination of Albendazole and Mebendazole in Pharmaceutical Formulations Based on Modified Sonogel Carbon Paste Electrodes with Perovskite-Type LaFeO₃Nanoparticles

Abstract

Differential pulse voltammetric determination of albendazole and mebendazole in pharmaceutical formulations based on modified sonogel carbon paste electrodes with Perovskite-type LaFeO3 nanoparticles.

Predictive Modelling to Study the Electrochemical Behaviour of PdO, TiO2 and Perovskite-Type LaFeO3 Modified Carbon Paste Electrodes

“…Mineral oil, Carbon graphite, Palladium oxide and Titanium IV Isopropoxide were purchased from (Sigma-Aldrich, St. Louis, MO, USA). Perovskite-Type LaFeO3 herein employed was produced and characterized according to previously described protocol [4].…”

“…All pro-portions are listed in Table 1. The modifications herein employed were subjected to scanning electron microscopy and elemental characterization in previous works by our group [4,5]. The experimental conditions for CV were: scan rate (υ) of either: 12.5; 25; 50; 100; 250 or 500 mV s -1 , and scan range of -0.5 to 1.0.…”

“…Moreover, modifications are easily feasible through direct addition of modifying agents, which may be of either organic or inorganic nature. The use of CP electrodes can furthermore lead to higher reproducibility, as the surface is renewed prior to each analysis, therefore limiting the impact of electrode fouling [3,4].…”

Oxidative Coupling Reaction for Micro Trace Analysis of Mebendazol Residual with p-bromoaniline in Presence of n- bromosuccinimide

“…Various analytical method is found for the assay of MBZ in different formulation dosage including UV-visible spectrometry (3-7), highperformance liquid chromatography (8-11), selective membrane sensor (12-14) and potentiometric analysis (14). The present work stand on oxidation of hydrolyzed MBZ in the presence of NBS then coupling with 4-BA to get a paled orang complex absorbed at 434 nm at pH 9.…”

Raman Spectroscopy vs Voltammetry: A Voltammetric Approach to Elucidate Different Chemicals in a Range of Pharmaceutical Tablets

“…However, these techniques are limited by the low reproducibility, and there is a clear need to evaluate and propose the use of sensors that are easy to clean and that guarantee the recognized advantages of electroanalysis. Hence, the use of graphite pencil electrodes (GPE) has proven to be a useful and efficient and low cost tool for the determination of drugs in pharmaceutical formulations, without many of the drawbacks found in other methods [4][5][6].…”
