An overview of capillary electrophoresis in element speciation analysis of the environment
(Bentham Science Publishers, 2014-04)
This article focuses on the main developments in element speciation analysis by capillary electrophoresis (CE) since the 1990s. A brief description of the main techniques employed in CE analysis has been reviewed with ...
Scanned stripping chronopotentiometry at bismuth film rotating disc electrodes: a method for quantitative dynamic metal speciation
(CSIRO Publishing, 2014-01-01)
Environmental contextElectroanalytical methods have found wide application in trace metal speciation analysis in environmental systems. The need to find functional alternatives to mercury electrodes for in situ speciation ...
TRACE METAL THERMODYNAMIC SPECIATION WITH HUMIC SUBSTANCES: THE NICA-DONNAN MODEL
(Soc Brasileira Quimica, 2017-10-01)
This work presents a critical overview of the NICA-Donnan model for trace metal thermodynamic speciation with humic substances obtained from natural organic matter in soils, natural waters and anthropogenic sources. A first ...
Mercury speciation in contaminated soils by thermal release analysis

Towards field trace metal speciation using electroanalytical techniques and tangential ultrafiltration
In this work we propose a trace metal speciation methodology to determine the total, free and ultrafiltered (<1 KDa) metal fractions using electrochemical methods (SCP and AGNES) and tangential ultrafiltration (UF) experiments ...
