Journal ArticleDOI
Arsenic fractionation in soils using an improved sequential extraction procedure
Walter W. Wenzel,Natalie Kirchbaumer,Thomas Prohaska,Gerhard Stingeder,Enzo Lombi,Domy C. Adriano +5 more
TL;DR: In this article, the authors developed and tested a sequential extraction procedure (SEP) for As by choosing extraction reagents commonly used for sequential extraction of metals, Se and P, including NH 4 NO 3, NaOAc, NH 2 OH·HCl, EDTA, NH 4 OH and NH 4 F, were shown to either have only low extraction efficiency for As, or to be insufficiently selective or specific for the phases targeted.

The role of DOM sorption to mineral surfaces in the preservation of organic matter in soils.
Klaus Kaiser,Georg Guggenberger +1 more
TL;DR: In this paper, the authors investigated the role of dissolved organic matter (DOM) in the preservation of organic matter in marine sediments and found that DOM sorption contributes considerably to the accumulation and preservation of OM in soil.
Journal ArticleDOI
Rapid assay for microbially reducible ferric iron in aquatic sediments.
TL;DR: A newly developed chemical assay for microbially reducible iron based on the reduction of poorly crystalline ferric iron by hydroxylamine under acidic conditions provides a correction for the high concentrations of solid ferrous iron which may also be extracted from sediments with acid.

Anion Adsorption by Soils and Soil Materials
TL;DR: In this article, the authors reviewed the work done with soils and with hydrous oxides of iron and aluminum, with particular reference to mechanisms and structural aspects of anion adsorption.
