TLDR
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.About:

Stabilization of As, Cr, Cu, Pb and Zn in soil using amendments – A review
TL;DR: An overview of data published during the last five years on the immobilization of one metalloid, As, and four heavy metals, Cr, Cu, Pb and Zn, in soils, finds that Zn can be successfully immobilized in soil by phosphorus amendments and clays.

Role of metal-reducing bacteria in arsenic release from Bengal delta sediments
Farhana Islam,Andrew G. Gault,Christopher Boothman,David A. Polya,John M. Charnock,John M. Charnock,Debashis Chatterjee,Jonathan R. Lloyd +7 more
TL;DR: It is shown that anaerobic metal-reducing bacteria can play a key role in the mobilization of arsenic in sediments collected from a contaminated aquifer in West Bengal and that, for the sediments in this study, arsenic release took place after Fe(iii) reduction, rather than occurring simultaneously.

Arsenic transformations in the soil-rhizosphere-plant system: fundamentals and potential application to phytoremediation.
Walter J. Fitz,Walter W. Wenzel +1 more
TL;DR: This paper proposes a conceptual model of the fate of As in the soil-rhizosphere-plant system by integrating the state-of-the art knowledge available in the contributing disciplines and discusses research needs and the potential application of rhizosphere processes to the development of phytoremediation technologies for As-polluted soils.

Sequential extraction procedure for the speciation of particulate trace metals
TL;DR: In this paper, an analytical procedure involving sequential chemicai extractions was developed for the partitioning of particulate trace metals (Cd, Co, Cu, Ni, Pb, Zn, Fe, and Mn) into five fractions: exchangeable, bound to carbonates, binding to Fe-Mn oxides and bound to organic matter.

Iron Oxide Removal from Soils and Clays by a Dithionite-Citrate System Buffered with Sodium Bicarbonate
TL;DR: In this article, the bicarbonate-buffered Na2S2O4-citrate system was used for removing free iron oxides from latosolic soils, and the least destructive of iron silicate clays.
