Towards the abatement of environmental mercury pollution: An electrochemical characterization
(Elsevier B.V., 2006-03-15)
Electrochemical experiments in acetic acid-acetate buffer (pH 4.5) are conducted in order to understand metallic and ionic mercury adsorption processes on the pyrite surface. The nature as well as the extent of the spontaneous ...
Reduction of mercury(II) by tropical river humic substances (Rio Negro) - A possible process of the mercury cycle in Brazil
(Elsevier B.V., 2000-12-04)
The evolution of elemental Hg from its environmental compounds has already been supposed to be an important process within the global mercury cycle. The present study characterizes the abiotic reduction of Hg(II) ions by ...

Indirect cathodic-stripping voltammetric determination of ceftazidime as a mercury salt
(Elsevier B.V., 1998-07-03)
At accumulation potentials close to +0.1 V at a hanging mercury drop electrode, ceftazidime is accumulated at pH 9.5, probably in a hydrolysed or otherwise chemically altered form, in an anodic process to give an adsorbed ...

Determination of mercury in agroindustrial samples by flow-injection cold vapor atomic absorption spectrometry using ion exchange and reductive elution
(2000-03-06)
A flow-injection system with a Chelite-S® cationic resin packed minicolumn is proposed for the determination of trace levels of mercury in agroindustrial samples by cold vapor atomic absorption spectrometry. Improved ...
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: ...
