Gold-based screen-printed sensor for detection of trace lead
TL;DR: In this paper, a gold-based screen-printed sensor was used for lead detection in combination with square wave anodic stripping voltammetry (SWASV) and the optimized parameters allowed the detection of micrograms per litre of lead concentrations following short analysis time.
Journal ArticleDOI
The voltammetric approach in trace metal chemistry of natural waters and atmospheric precipitation
TL;DR: In this article, the salient aspects of the overall analytical procedure are discussed and the substantial possibilities for application are emphasized by a number of examples taken from recent work, including voltammetry with toxicological significance in the ecology of aquatic systems and atmospheric precipitations.

Determination of Trace Mercury in Saltwaters at Screen-Printed Electrodes Modified with Sumichelate Q10R
TL;DR: In this article, the results of a study on the determination of trace levels of mercury in natural saltwaters using screen-printed carbon electrodes modified with Sumichelate Q10R, a chelating resin containing dithiocarbamate groups, which binds mercury strongly and selectively are reported.
Journal ArticleDOI
Voltammetric determination of trace mercury in chloride media at glassy carbon electrodes modified with polycationic ionomers
TL;DR: In this article, a study of the ion exchange voltammetric behavior of the tetrachloromercurate (II) complex at Tosflex-modified electrodes indicates the efficient incorporation of the analyte into the polymeric coating to which a remarkable positive shift in the reduction potential of HgCl 2−4 to Hg 0 is associated.

TL;DR: The procedure described below permits the determination of mercury concentrations as low as 5 ng Hg l-l, in 50-ml samples with minimum pre-treatment, because of the extremely low concentration of mercury in sea-water.
