Electrical decontamination of soil

Journal of Electrostatics, 1997
Abstract A technique of electrical decontamination of soil using electrokinetic phenomena has been developed. Experimental and theoretical studies show that the electroosmosis effects depend greatly on electric field intensity and pore thickness.

Decontamination of pesticides in soils

1969
The soil, as a medium for decontamination, offers a large number of processes by which organic substances can be destroyed. As such, progressive accumulation of organic pesticides would appear to be unlikely. Unfortunately, the chemical and physical properties of certain insecticides and herbicides afford them a degree of stability against the natural ...

In Situ Decontamination of Soil

Journal of Canadian Petroleum Technology, 1998
Abstract Methods for decontamination of soil in situ are receiving increased attention, as the requirement to clean these sites has become a national concern. The continual and costly liability is an important corporate incentive to clean contaminated soils.

Decontamination of soil polluted by hydrocarbons

Materials Today: Proceedings, 2022
Abstract The objective of this work is to study the coupling power of hydrogen peroxide and ozone (Peroxone) on the decontamination of soil contaminated by Total Petroleum Hydrocarbons (TPH). The oxidation takes place simultaneously by the exchange of electrons, which will activate the decomposition of hydrogen peroxide into OH radicals.

Applications of Bentonite to Soil Decontamination

Revista de Chimie, 2018
A calcium bentonite from Orasu Nou deposit (Satu Mare Romania) was used as raw material. We have conducted laboratory experiments to determine the influence of bentonite on the degree of heavy metal retention. It has been observed that the rate of retention increases as the heavy metal concentration decreases.

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.

Biotechnological Aspects of Soil Decontamination

2014
Soils have been subjected to several contaminants that vary in concentration and composition. Soil pollution causes significant damage to the environment and human health as a result of their mobility and solubility. Significant progress has been made in regulating soil pollution, with a parallel development of methodologies for soil assessment and ...

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.
