Determination of paracetamol: Historical evolution

“…The performance of the methods was enhanced by introducing postcolumn on-line photochemical derivatisation in combination with diode-array detection. The column effluents were subjected on-line to UV irradiation (254 nm) and the char- a.c. polarography After elimination of protein by perchloric acid, followed by reaction with nitrous acid in acidic medium, the nitro derivative is measured at pH 10 [225] Pharmaceutical dosage form Polarography Paracetamol and salicylamide after treatment with nitrous acid [226] Blood plasma (rat serum) and tablets Differential pulse voltammetry Oxidation of PCT on a carbon paste electrode [227] Urine and pharmaceutical preparations Differential pulse voltammetry Using a pumice mixed carbon paste electrode [228] Pharmaceutical products Cyclic voltammetry Using crude extracts of several fruits and vegetables as the sources of peroxidise for use in carbon paste biosensors [229] Pharmaceutical products Differential pulse voltammetry Simultaneous determination of paracetamol, ascorbic acid and caffeine; using a glassy carbon electrode [230] Pharmaceutical products Differential pulse stripping voltammetry Paracetamol and phenobarbital; using a glassy carbon electrode; assisted by chemometrics (PLS and PCR methods) [231] Plasma Amperometric Electrochemical oxidation of PCT; the technique has been adapted for assay in biological fluids by the use of a permselective cellulose acetate membrane, and an outer diffusion-limiting, microporous polycarbonate membrane treated with dimethyldichlorosilane to impart biocompatibility [232] Tablets…”

Determination of analgesics in pharmaceutical formulations and urine samples using nano polypyrrole modified glassy carbon electrode

“…Electrochemical detection and cyclic voltammetric determination of AAP were reported [8,12]. The differential pulse voltammetric behavior of some drugs, including AAP at various conducting polymers [13] and at pumice mixed carbon electrodes [14], have been examined and reviewed [15]. AAP was determined by voltammetric method using C60-modified glassy carbon electrode [1].…”
