Arsenic speciation by X-ray spectroscopy using resonant Raman scattering
(Springer, 2013-12)
We have shown that X-ray resonant Raman scattering (RRS) spectroscopy can be used to analyze arsenic species. This work is pioneer in the area and an important work on the result interpretation is necessary in the future. ...
Differential tissue accumulation of arsenic and heavy metals from diets in three edible fish species
(Wiley, 2013-12)
Three different commercial fish species Odontesthes bonariensis, Rhamdia quelen and Oreochromis niloticus and fish feed were collected from four aquaculture farms. Heavy metal (Cd, Cr, Cu, Fe, Mn, Pb and Zn) and arsenic ...
Influence of redox potential (eh) on the availability of arsenic species in soils and soils amended with biosolid
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Cationic polyelectrolytes. Synthesis, characterization and application in analysis and removal of arsenic.
(Universidad de Concepción.Facultad de Ciencias Químicas, 2010)
Arsenic occurs in a variety of forms and oxidation states and is a very toxic element. The main arsenic species present in natural waters are arsenate (oxidation state V) and arsenite ions (oxidation state III). The ...
Biosorption of arsenic from groundwater using Vallisneria gigantea plants. Kinetics, equilibrium and photophysical considerations
(Elsevier, 2015-06)
Arsenic (V) uptake from groundwater by using Vallisneria gigantea plants was studied using batch experiments. Reflectance and fluorescence of intact plants were investigated and changes in photophysical properties following ...
Ionic liquid as ion-pairing reagent for liquid-liquid microextraction and preconcentration of arsenic species in natural waters followed by ETAAS
(Royal Society of Chemistry, 2010-06)
A simple and highly efficient microextraction methodology was developed for arsenate [As(V)], arsenite [As(III)] and organic arsenic (i.e., DMA and MMA) preconcentration and determination based on the novel use of ...
Adsorption/desorption of arsenic by tropical peat: influence of organic matter, iron and aluminium
(Taylor & Francis Ltd, 2015-01-17)
The objective of this work was to investigate the interaction of arsenic species (As(III) and As(V)) with tropical peat. Peat samples collected in Brazil were characterized using elemental analysis and C-13 NMR. Adsorption ...
