Screen-printed carbon electrode modified with poly-L-histidine applied to voltammetric determination of chromium (VI)
(2006-12-01)
The present work reports the use of a screen-printed carbon electrode (SPCE) modified by poly-L-histidine film to determine chromium (VI). Stable films can be formed by direct addition of PH solution 1 % (w/v) on the ...

Sensitive determination of nitrofurantoin by flow injection analysis using carbon nanofiber screen printed electrodes
(2013)
In this work, a new method to quantify nitrofurantoin in aqueous media using a flow injection system connected to commercially available screen-printed carbon nanofibers was developed. A pretreatment of the screen-printed ...
Determination of isoniazid in human urine using screen-printed carbon electrode modified with poly-L-histidine
(Elsevier B.V. Sa, 2010-02-01)
A sensitive voltammetric method for trace measurements of isoniazid (INZ) in synthetic human urine sample is described. The method is based on its electroreduction at -0.98 V vs. Ag/AgCl on screen-printed carbon electrode ...

Aspects of cathodic stripping voltammetry at the hanging mercury drop electrode and in non-mercury disposable sensors
(Wiley-Blackwell, 2000-10-01)
Cathodic stripping voltammetry (CSV) and accumulation at the hanging mercury drop electrode are reviewed briefly. Proposals in a recent IUPAC technical report are considered. Three recent developments in CSV are discussed: ...

Flow injection amperometric determination of procaine in pharmaceutical formulation using a screen-printed carbon electrode
(Elsevier B.V., 2007-01-04)
A rapid and simple method for procaine determination was developed by flow injection analysis (FIA) using a screen-printed carbon electrode (SPCE) as amperometric detector. The present method is based on the amine/hydroxylamine ...
