DOI: 10.1016/j.chemosphere.2019.125517
Abstract: The speciation and mobility of As are controlled by both Fe and Mn (oxyhydr)oxides through a series of surface complexation and redox reactions occurring in the environment, which is also complicated by the solution chemistry… read more here.

DOI: 10.1016/j.gca.2016.10.049
Abstract: Abstract Arsenic (As) is a widespread and problematic pollutant that can be derived from natural or anthropogenic sources. Iron (oxyhydr)oxides readily sorb As and thus play critical roles in As cycling in terrestrial environments; however,… read more here.
