Heavy metal adsorption on iron oxide and iron oxide-coated silica : macroscopic, spectroscopic, and modeling studies
To accurately model metal mobility and bioavailability in soils and sediments, systematic sorption studies are needed using representative and well-characterized minerals. Two important surfaces are iron oxide and silica, which are ubiquitous and associated with one another in the environment …

Chemically activated carbon using peat soil for heavy metals adsorption in industrial wastewater
… soil activated carbon (PSAC) for the removal of heavy metal ions in industrials wastewater. Activated carbon from peat has successfully produced by chemical activation process using sulphuric acid as activating agents. The effect of heating temperature on the carbon content, the physical and …

Chemical heterogeneity of glaciofluvial deposits: Outcrop study and implications for reactive transport
… (1) identify the sediment properties controlling heavy metal adsorption, (2) evaluate the extent to which geologic information can be used to characterize their spatial variation, and (3) assess the impact of spatial variations on heavy metal transport. Four hundred seventy-six, spatially-located …
