Implications of aqueous silica sorption to iron hydroxide: mobilization of iron colloids and interference with sorption of arsenate and humic substances
Article Abstract:
Sorbed silica in contact with an iron hydroxide surface is studied for its effect on humic substance removal, arsenate removal, and particle stability. The interactions are plotted for percentages of arsenic removal, iron mobilization, and fulvic acid removal.

Thiosulfate enhances silver uptake by a green alga: role of anion transporters in metal uptake
Article Abstract:
The green alga Chlamydomonas reinherti's silver uptake was measured in the presence or absence of ligands (chloride and thiosulfate) in defined inorganic media in this laboratory experiment. The choice of ligand used to buffer the free silver concentration proved to impact the silver accumulation. Studies concluded that sulfate acts as a competitive inhibitor of the uptake mechanism, and silver-thiosulfate complexes are transported across the plasma membrane by sulfate/thiosulfate transport systems.
