Control of the mobilization of arsenic and other natural pollutants in groundwater by calcium carbonate concretions in the Pampean Aquifer, southeast of the Buenos Aires province, Argentina
(Elsevier, 2019-07)
The water supply for human consumption in the Chaco-Pampean region in Argentina is restricted by the low quality of groundwater due to elevated concentrations of arsenic and other trace elements. Previous studies indicated ...
Influence of redox potential (Eh) on the availability of arsenic species in soils and soils amended with biosolid
(PERGAMON-ELSEVIER SCIENCE LTD, 2008-08)
A Study was done on the influence of redox potential on the mobility and availability of the various arsenic chemical forms in a Mollisol soil from central Chile amended with biosolid. Arsenic availability was strongly ...
The role of loess weathering in the groundwater chemistry of the Chaco-Pampean Plain (Argentina)
(Elsevier, 2020-08)
The Chaco-Pampean Plain (CPP), Argentina, is one of the most extensive loess areas in the world, higlhly productive in terms of agriculture and livestock and with a generalized groundwater signature of Na-HCO3 water type. ...
Enhanced As (V) Adsorption Properties in Sn-Substituted Goethites - Changes in Chemical Reactivity and Surface Characteristics
(International Journal of Innovative Research in Engineering & Management, 2015-11)
In this work, the adsorption of arsenic (V) onto crystalline substituted goethites was studied for samples with different Sn- contents. The highest Sn-content of the prepared samples was 5.5 (expressed as 100?[Sn]/[Sn]+[Fe]) ...
