Mobility and Adsorption of Trace Elements in a Coal Residues-Affected Swamp adsorption of these metals to the sediments. The sediments collected from three adjacent sites showed considerable heterogeneity but had a uniform pH approximating 6.0. Three periodic collections of sediment cores (0–20 cm) from two sites and surface sediments (0–10 cm) of 3. site were analyzed for

Potential Use of Fly Ash to Remove Cadmium from Aqueous Systems availability, it is necessary to investigate alternate adsorbent sources. Fly ash is, an inexpensive and abundantly available by-product from thermal power plants that utilizes coal for the production of energy. A study was conducted to (i) identify the optimum conditions for Cd adsorption by fly a

Selenium and Molybdenum Adsorption on Kaolinite Clay Mineral Coated with Hydrous Oxides of Iron and been used to create technogenic soils for reclamation of abandoned mine lands. Fly ash contains toxic trace elements such as selenium and molybdenum that can leach into the groundwater from ash treated soils. In abandoned acid mine lands, oxidation of pyrite generates acidity and dissolved Fe and Al

The Effect of Flue Gas Desulfurization Residue on Corn (, L.) Growth and Leachate Salinity: Multiple several cropping periods. Dry biomass and elemental composition of crop plants were measured, as well as the quality and chemical composition of soil and leachate collected from treated mesocosms. Data collected in the first year following FGD amendment showed no effect on the germination of corn .
