Insights into the biogeochemical transformation, environmental impacts and biochar-based soil decontamination of antimony.

Environmental Research
Every year, a significant amount of antimony (Sb) enters the environment from natural and anthropogenic sources like mining, smelting, industrial operations, ore processing, vehicle emissions, shooting activities, and coal power plants.

Iron-based persulfate activation process for environmental decontamination in water and soil.

Chemosphere, 2020
Sulfate radical based advanced oxidation processes have been extensively studied for the degradation of environmental contaminants. Iron-based materials such as ferrous, ferric, ZVI, iron oxides, sulfides etc., and various natural iron minerals have been

Water and soil decontamination of toxic heavy metals using aminosilica-functionalized-ionic liquid nanocomposite

Journal of Molecular Liquids, 2018
A chemical modification method is presented to establish a surface functionalization procedure of amino modified nanosilica (NS-amine) with 1-(3-cyanopropyl)-3-methylimidazolium-bis(trifluoromethylsulfonyl) type of ionic liquid, [CN-C3-MIm]+[NTf2]− for ...

Decontamination of Metal-Containing Soils

1995
Methods of removing metals from spoils derived from metalliferous mining were assessed as an alternative to traditional methods of land reclamation. Both enhanced gravity separation and chemical leaching were effective for oxidised spoils. The possibility of combined process routes in order to maximise metal removal are discussed.

Decontaminating soil with enzymes

Environmental Science & Technology, 1992
Xenobiotics are manmade compounds often introduced into the environment at concentrations that cause undesirable effects. They can be transformed as a result of biotic and abiotic processes, leading to changes in their chemical state and ultimately in their toxicity and reactivity.

Ecological recovery of decontaminated soil.

1988
Once polluted soil is thermically cleaned up, a dead product is the result. However, the Dutch government emphasizes the so-called principle of multifunctionality of the soil. The most vulnerable function of the soil is the ecological function. To assess the possibilities of ecological recovery of cleaned soils, a field experiment was performed in a ...

Decontamination of radioactive cesium in soil

Journal of Radioanalytical and Nuclear Chemistry, 2014
Agricultural soil containing radioactive cesium was decontaminated using an extraction method involving aqueous potassium solutions. Results demonstrated that the potassium solution could extract radioactive cesium from soil artificially contaminated with 137Cs, although extraction rate decreased as time after contamination increased.

Soil Pollution and Decontamination in Spain

European Energy and Environmental Law Review, 2002
Summary: In Spain there is no legal framework that collects all aspects of laws relating to the environment. In the absence of over-arching legislation this article examines the control and remediation of soil pollution in Spain looking first at administrative law aspects — its concepts; the identification of polluted soil; registration of polluted ...

Solvent extraction and tandem dechlorination for decontamination of soil

Chemosphere, 2001
The United States Environmental Protection Agency (US EPA) guidelines allow removal of polychlorinated biphenyls (PCBs) from soils via solvent extraction. This option holds promise for removal of other recalcitrant organic contaminants as well. A study was undertaken to evaluate the effectiveness of solvent extraction with two tandem degradation ...

Decontamination of soils containing PAHs by electroremediation: A review

Journal of Hazardous Materials, 2010
During the last years, the anthropogenic sources have contributed to organic compound penetration into the environment. One large group of persistent and toxic contaminants is the hydrophobic organic contaminants. Among them, polycyclic aromatic hydrocarbons (PAHs) have been recognized as a representative group of these pollutants with low solubility ...
