The Effects of Iron(ii) on Arsenic(iii) Oxidation and Arsenic Sorption/desorption on Manganese Oxides

Review of the Surface Chemical Heterogeneity of Bacteriogenic Iron Oxides: Proton and Cadmium Sorption

This review focuses on the detailed characterization of proton and metal reactivity on the surface of bacteriogenic iron oxides (BIOS). This substance is composed of a highly porous matrix of ferrihydrite intermixed with intact and fragmented Gallionella ferruguinea cells. Studies concerning proton and metal cation binding to the BIOS were designed to assess their surface chemical heterogeneity...

Role of Surface Precipitation in Copper Sorption by the Hydrous Oxides of Iron and Aluminum.

Isotherms were developed at pH 6.9 for adsorption (ADS) and coprecipitation (CPT) of Cu by hydrous oxides of Fe (HFO) and Al (HAO) to study the role of sorbate/sorbent ratio in metal cation removal. For low sorbate/sorbent conditions, HFO had a higher Cu retention capacity than HAO regardless of contact methodology. For either oxide, CPT was consistently more effective than ADS in removing Cu f...

environmental effects of gol-e-gohar iron ore mine on groundwater of the area

gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...

DIVISION S-2—SOIL CHEMISTRY Selenate and Selenite Sorption on Iron Oxides: An Infrared and Electrophoretic Study

We studied selenate and selenite sorption by amorphous Fe oxide [am-Fe(OH)3] and goethite (a-FeOOH) as a function of time (25 min-96 h), pH (3-12), ionic strength (0.01-1.0 M NaCl), and total Se concentration (0.0001-1.0 M). We examined sorbed selenate and selenite by in situ attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy, diffuse reflectance infrared Fourier tr...
