Direct Determination of Acetaminophen in Plasma by Differential Pulse Voltammetry
Journal of Pharmaceutical Sciences, 1978A 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.

Determination of Zidovudine in Pharmaceuticals by Differential Pulse Voltammetry
Analytical Letters, 2010The 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.

Determination of promethazine by anodic differential-pulse voltammetry
Analytica Chimica Acta, 1984Abstract 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.

Revisiting the nitrite reductase activity of hemoglobin with differential pulse voltammetry
Analytica Chimica Acta, 2020Nitric oxide (NO) is an omnipresent signalling molecule in all vertebrates. NO modulates blood flow and neural activity. Nitrite anion is one of the most important sources of NO. Nitrite is reduced to NO by various physiological mechanisms including reduction by hemoglobin in vascular system.

Differential-pulse adsorptive stripping voltammetry of chlorhexidine
The Analyst, 1991Chlorhexidine 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 ...

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 indole in shrimps by differential-pulse voltammetry in an emulsified medium
The Analyst, 1990A method has been developed to determine indole in shrimps by differential-pulse voltammetry at a Pt electrode in an emulsified medium, after extraction into hexane - ethyl acetate (49 + 1). The standard additions method was used in order to minimise the matrix effect.

Differential pulse adsorptive stripping voltammetry of osmium-modified peptides
Bioelectrochemistry, 2002Complexes of osmium tetroxide with nitrogen ligands were developed and used in our laboratory as probes of the DNA structure. Here, we show that the complex of osmium tetroxide with 2,2'-bipyridine (Os,bipy) can be used for modification and electrochemical detection of proteins at neutral pH.

Simultaneous determination of three herbicides by differential pulse voltammetry and chemometrics
Journal of Environmental Science and Health, Part B, 2011A novel differential pulse voltammetry method (DPV) was researched and developed for the simultaneous determination of Pendimethalin, Dinoseb and sodium 5-nitroguaiacolate (5NG) with the aid of chemometrics. The voltammograms of these three compounds overlapped significantly, and to facilitate the simultaneous determination of the three analytes ...

Determination of chlorite in drinking water by differential pulse voltammetry on graphite
Analytical and Bioanalytical Chemistry, 2004The chlorite ion is an unavoidable by-product of the disinfection of drinking water by means of chlorine dioxide. The maximum concentration values of chlorite accepted in many countries' regulations range from 0.2 to 1.0 mg L(-1). A simple, inexpensive and quickly set up voltammetric procedure for the on-site determination of chlorite in drinking water
