Direct Determination of Acetaminophen in Plasma by Differential Pulse Voltammetry

Journal of Pharmaceutical Sciences, 1978
A rapid, simple method for the direct determination of acetaminophen in plasma at toxic levels was developed. The method is based on the oxidation of the phenolic moiety of acetaminophen at a carbon paste electrode in a differential pulse voltammetric mode. Linear calibration curves are obtained from 20 to 400 microgram/ml.

Differential Pulse Voltammetry of Nitrobenzene

ECS Meeting Abstracts, 2018
Removal of nitrobenzene from water is of current interest due to its toxicity (1) as a mutagen and carcinogen. Water sample with initial known concentration of nitrobenzene (4mM) was taken and treated with adsorbent: spent tea leaves (2). After treatment with adsorbent nitrobenzene was analyzed using such electrochemical techniques (3) as ...

Determination of cadmium by differential pulse adsorptive stripping voltammetry

Journal of Pharmaceutical and Biomedical Analysis, 2000
A study of the adsorptive stripping voltammetry of cadmium on a mercury drop electrode is reported in which 2-mercapto-5-phenyl-amino-1,3,4-thiadiazole (MPATD), synthesized at home has been used as a chelating agent. The most suitable operating conditions and parameters such as buffer, pH, deposition potential, deposition time, ligand concentration ...

Differential linear scan voltammetry: analytical performance in comparison with pulsed voltammetry techniques

Analytical and Bioanalytical Chemistry, 2013
We report here on differential linear scan voltammetry, DLSV, that combines the working principles of linear scan voltammetry, LSV, and the numerous existing pulsed voltammetry techniques. DLSV preserves the information from continuous interrogation in voltage and high accuracy that LSV provides about electrochemical processes, and the much better ...

Determination of promethazine by anodic differential-pulse voltammetry

Analytica Chimica Acta, 1984
Abstract A differential-pulse voltammetric method is described for the determination of promethazine hydrochloride. The method is based on the anodic oxidation of promethazine on a glassy carbon electrode at + 0.64 V vs. SCE in Prideaux buffer of pH 2.3.

Determination of Zidovudine in Pharmaceuticals by Differential Pulse Voltammetry

Analytical Letters, 2010
The zidovudine (AZT) has been extensively used in the treatment of HIV patients due to its antiretroviral activity. The quality control of this substance in drugs is of outstanding importance to public health because of its undesirable effects and short therapeutic interval.

Differential-pulse adsorptive stripping voltammetry of chlorhexidine

The Analyst, 1991
Chlorhexidine gluconate was shown to adsorb onto a hanging mercury drop electrode and to be amenable to quantification by adsorptive stripping voltammetry. A sensitivity of 1 × 10–7 mol dm–3 was easily achieved by simply immersing the electrode in a stirred solution (pH 9.7 ammonia-ammonium acetate buffer) of the drug for a fixed time (60 s), at a ...

Determination of Monomethylcadmium in the Environment by Differential Pulse Anodic Stripping Voltammetry

Analytical Chemistry, 1996
A differential pulse anodic stripping voltammetric (DPASV) method was used to differentiate between the cadmium species Cd(2+) and MeCd(+) (Me = methyl) in aquatic systems. These two species show peaks in the DPASV voltammogram which differ by 112 mV.

Determination of isopropylmethylphenols in black seed oil by differential pulse voltammetry

Phytochemical Analysis, 2004
AbstractA differential pulse voltammetric method is presented for the determination of isopropylmethylphenols (carvacrol and/or thymol) in phytotherapeutic black seed oils. The voltammetric behaviours of these phenols were examined in various buffer systems over the pH range 3.5–10.0.

Determination of nickel in human nails by adsorption differential-pulse voltammetry

The Analyst, 1985
A procedure is described for the determination of nickel in human nails, which consists in a simple wet digestion followed by quantitation by adsorption differential-pulse voltammetry. This procedure produced more reliable results for low nickel levels than atomic-absorption spectrometry; for unexposed individuals, mean values for nickel in finger-and ...
