Biochar (BC) and magnetite (Fe3O4) nanoparticles (MNP) have both received considerable recent attention in part due to their potential use in water treatment. While both are effective independently in the removal of a range of anionic metals from aqu

Highlights • The adsorption of Co, Ni, Cu, and Zn to Synechococcus sp PCC 7002 was studied using a surface complexation modelling approach. • A surface complexation model was developed to determine the thermodynamic binding constants of Co, Ni, C

Ratios of phosphorous (P) to iron (Fe) in Precambrian banded iron formations (BIFs) have previously been used to estimate dissolved seawater phosphate concentrations in the ancient oceans. Such studies rely on an assumed composition of the primary ir

Photoferrotrophs repel iron to deposit banded iron formations and contribute methane to the atmosphere during the Archean Eon.
Banded iron formation (BIF) deposition was the likely result of oxidation of ferrous iron in seawater by either oxygen

Open pits, which remain after uranium (U) mining operations cease, can form meromictic lakes that develop suitable conditions for the containment of dissolved and colloidal metals. In this study, the distribution and speciation of U, nickel (Ni), and

Banded iron formations are critical to track changes in Archaean to Palaeoproterozoic ocean chemistry, with deposition triggered by water column iron oxidation. Recently, however, it was suggested that reduced iron minerals were the primary precipita

Banded iron formations (BIF) represent one of the few chemical sedimentary archives available for exploring the redox state of the Precambrian atmosphere-ocean system and the marine availability of biologically critical trace nutrients through time.
