TLDR
In this article, the authors investigated the kinetic effect of specific adsorption interactions on the chemical reduction of uranyl (UVIO22+) by ferrous iron, and derived a rate law for surface-catalyzed U(VI) reduction by Fe(II), d[U(VI)] dt =−k[≡ Fe III OFe II OH 0 ][U( VI)] ads where the bimolecular rate constant k has a value of 399 ± 25 M−1 min−1 at 25°C.About:

TL;DR: In this paper, the role of competing ions in the mobilization of arsenic (As) by surface complexation modeling of the temporal variability of As in groundwater was assessed by using two SCMs, developed for ferrihydrite and goethite, to account for the temporal variation of As(III) and As(V) concentration, monitored in shallow groundwater of Bengal Basin over a period of 20 months.
