Hydrothermal-treatment desorption of cesium from clay minerals: The roles of organic acids and implications for soil decontamination.

Water Research, 2020
The adsorption and desorption of cesium (Cs) on clays of contaminated soil in a rhizosphere zone can be greatly affected by various biogeochemical processes, the timespans of which are usually months to years.

Sustainable decontamination of heavy metal in wastewater and soil with novel rectangular wave asymmetrical alternative current electrochemistry.

Journal of Hazardous Materials, 2022
A new concept of removal and recovery of heavy metals and simultaneous regeneration and reuse of ethylenediamine-tetraacetic acid (EDTA) in soil washing effluent containing metal-EDTA complexes is proposed, which is used to remediate heavy metal ...

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.

Photocatalytic soil decontamination

Chemosphere, 1992
Abstract A photocatalytic treatment is evaluated for the decontamination of soils containing 2-chlorophenol, 2,7-dichlorodibenzodioxin and atrazine. In the laboratory the contaminated soils were mixed with a photocatalyst (TiO2) in a aqueous slurry (up to 60 g L−1 of solid mixture) and exposed to simulated solar radiation.

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.

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 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 ...

Selective removal of radiocesium from micaceous clay for post-accident soil decontamination by temperature-controlled Mg-leaching in a column.

Journal of Hazardous Materials, 2019
The effective and efficient removal of radioactive Cs from contaminated soil is highly urgent for the nuclear post-accident remediation. In present study, we achieved rapid Cs desorption from both a typical micaceous clay (i.e., vermiculitized biotite ...

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.
