Direct determination of lead in blood by differential pulse stripping voltammetry
Clinica Chimica Acta, 1987A simple and rapid method for determination of lead in blood by differential pulse stripping voltammetry (DPS) without preliminary mineralization of the sample, is described. Lead determination was performed in native samples of blood in the electrolyte of Britton-Robinson buffer (pH 5-5.5).

Determination of isopropylmethylphenols in black seed oil by differential pulse voltammetry
Phytochemical Analysis, 2004AbstractA 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.

This work describes optimal conditions for the determination of chlorpromazine and thioridazine by DPV, with a detection limit of 4.0 x 10(-7)M (0.16 microg/ml). The well-defined peaks indicate that direct measurement in a medium of 0.03 M perchloric acid in acetonitrile is possible and the use of DPV is advantageous when small amounts are to be ...

Determination of nickel in human nails by adsorption differential-pulse voltammetry
The Analyst, 1985A 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 ...

Determination of lead in paint by differential-pulse anodic-stripping voltammetry
The Analyst, 1978A procedure for the determination of lead in paints by differential-pulse anodic-stripping voltammetry is presented. Only a few milligrams of sample are required for the analysis. Dry ashing with sodium carbonate as the flux has been found to be a simple and effective method for the destruction of the organic matrix. Samples of the dried paint of small

Determination of paracetamol in tablets and blood plasma by differential pulse voltammetry
Journal of Pharmaceutical and Biomedical Analysis, 1988Paracetamol, also known as acetaminophen (APAP) (N-acetyl-p-aminophenol), is a widely used non-narcotic analgesic and antipyretic agent. The determination of paracetamol is important for assessing stability for therapeutic monitoring and for possible toxicological effects.

Determination of gallium traces by differential pulse anodic stripping voltammetry
Fresenius' Zeitschrift für analytische Chemie, 1988The determination of gallium traces is carried out on the hanging drop mercury electrode in solutions of low ionic strength and in absence of complexing agents. At pH=3.2, where stable solutions are obtained, concentrations of 0.2 μg Ga l−1 are determinated with a standard deviation of 0.96% and a detection limit of 4 ng Ga l−1.

Abstract Differential pulse voltammetry (DPV) and related techniques are examined. The proposed treatment is valid for any pulse method performed at stationary plane or spherical electrodes in the case of simple reversible reactions with both redox forms soluble in solution.
