Journal ArticleDOI
Comparison of arsenic(V) and arsenic(III) sorption onto iron oxide minerals: implications for arsenic mobility.
Suvasis Dixit,Janet G. Hering +1 more
TL;DR: The sorption data indicate that, under most of the chemical conditions investigated in this study, reduction of As(V) in the presence of HFO or goethite would have only minor effects on or even decrease its mobility in the environment at near-neutral pH conditions.
Journal ArticleDOI
Processes controlling solubility of biogenic silica and pore water build-up of silicic acid in marine sediments
TL;DR: In this paper, the results of batch and flow-through reactions were combined with data on sediment composition and pore water silicic acid profiles to identify processes controlling the solubility of biogenic silica and the build-up of silica acid in marine sediments.
Journal ArticleDOI
Biogenic silica dissolution in the oceans: Reconciling experimental and field‐based dissolution rates
TL;DR: In this article, the observed variability in biogenic silica reactivity is consistent with results of experimental dissolution studies and the experimental data further imply that aluminum incorporation in the silica matrix, during biomineralization or after death of the organisms, enhances the preservation efficiency of biogenic opal in marine sediments.
Journal ArticleDOI
Sorption of Fe(II) and As(III) on goethite in single- and dual-sorbate systems
Suvasis Dixit,Janet G. Hering +1 more
TL;DR: In this article, the experimental data obtained in single-sorbate experiments were modeled using a diffuse double layer surface complexation model and used to predict and compare sorption in dual-sorborate systems.
Journal ArticleDOI
Surface chemistry and reactivity of biogenic silica
TL;DR: The surface chemistry of cultured diatoms was compared to that of biosiliceous material in Southern Ocean sediments, using potentiometric titrations and aluminum adsorption experiments as mentioned in this paper.
