The biogeochemistry of manganese and iron reduction in marine sediments
TL;DR: In this paper, the results of laboratory studies on the types of manganese and iron reduction that are known to occur in marine sediments, and then discuss the occurrence of these processes in different sedimentary environments.

Partitioning of trace metals in sediments: Relationships with bioavailability
TL;DR: In this article, a major fraction of the trace metals introduced into the aquatic environment is found associated with the bottom sediments, distributed among a variety of physico-chemical forms.

Adsorption of selenium by amorphous iron oxyhydroxide and manganese dioxide
Laurie S. Balistrieri,T. T. Chao +1 more
TL;DR: In this article, the authors compared and modeled the adsorption of selenium and other anions on a neutral to alkaline surface (amorphous iron oxyhydroxide) and an acidic surface (manganese dioxide).

Trace metals in oxic lake sediments: possible adsorption onto iron oxyhydroxides
TL;DR: In this article, the authors compared the results obtained from oxic lake sediments and the in situ measurement of trace metal concentrations in the associated pore waters in the area of Sudbury, Ontario, to those obtained for the adsorption of the trace metals onto amorphous iron oxyhydroxides in a NaNO3 medium.

Metal Interactions with Microbial Biofilms in Acidic and Neutral pH Environments.
TL;DR: Conditional adsorption capacity constants, obtained graphically from the data, showed that biofilm metal uptake at a neutral pH level was enhanced by up to 12 orders of magnitude over acidic conditions.

Surface ionization and complexation at the oxide/water interface
TL;DR: In this article, a method for determination of intrinsic ionization and complexation constants of oxide surface sites from potentiometric titration data is reported using these experimental properties and the stoichiometry of surface reactions, surface charge, σo, adsorption density, Γi, and diffuse layer potentials, ψd, at the oxide/water interface.
Journal ArticleDOI
Flocculation of dissolved organic and inorganic matter during the mixing of river water and seawater
TL;DR: In this paper, a new approach to estuarine studies is presented which establishes 1) the extent and salinity dependence of non-conservative behaviour; 2) composition and chemical form of removal products; and 3) abiological removal mechanisms.

Surface ionization and complexation at the oxide/water interface II. Surface properties of amorphous iron oxyhydroxide and adsorption of metal ions
James A. Davis,James O. Leckie +1 more
TL;DR: In this paper, the site-binding model for the electrical double layer of hydrous oxides reported in a previous paper is applied to the adsorption of metal ions from dilute solution and to complex heterogeneous systems, i.e., amorphous iron oxyhydroxide.

The equilibrium speciation of dissolved components in freshwater and sea water at 25°C and 1 atm pressure
TL;DR: In this paper, a data base summarising the stability constants of more than 500 complexes is used to calculate speciation pictures for 58 trace elements in model seawater (pH 8.2) and freshwaters (PH 6 and 9).

The adsorption of aquatic humic substances by iron oxides
TL;DR: In this article, the interaction of humic substances from Esthwaite Water with hydrous iron oxides (α-FeOOH, α-Fe2O3, amorphous Fe-gel) have been examined by measuring adsorption isotherms and by microelectrophoresis.
