Enhanced electrokinetic technologies with oxidization–reduction for organically-contaminated soil remediation

Electrokinetic remediation of inorganic and organic pollutants in textile effluent contaminated agricultural soil

“…The energy consumption was around 720 kW h m À3 .The cost of electrical energy consumed for this process was 83.3 dollars for cubic meter of soil (83.3 $ m À3 ) where initial required investment was not included. The cost analysis of the present study is nearer to Ren et al (2014).…”

Preparation and Modification of Biochar Materials and their Application in Soil Remediation

“…But the disadvantages are its high costs and the risk of secondary diffusion. Chemical remediation technologies mainly include immobilization-stabilization techniques, redox, chemical modification, surfactant cleaning, and organic matter improvement [6,7], but the chemicals used may cause secondary pollution to the environment. There is a long repair cycle in bioremediation technology and the repair effect is susceptible to external environmental factors.…”

New Laboratory Techniques on Soil Decontamination

“…Several types of soils and various methods of polluting at the laboratory level have been studied (Popa & Negoita 2016, Popa & Onutu 2016, Popa et al 2017. Among the methods of depollution applied at laboratory level less studied is the electrical method (Han et al 2004, Li et al 2018, Lycenko et al 2018, Ren et al 2014, Risco et al 2016a. Starting from literature data (Streche et al 2014) a device has been designed which involves the existence of electrodes mounted inside the soil sample polluted with a liquid petroleum product.…”
