SurfactantEnhanced Washing of Soils Contaminated with An old automotive industrial site loed at Mexico City with many years of operation and contaminated with heavy oil hydrocarbons, particularly spent oils, was assessed for restoration using the surfactant enhanced soil washing (SESW) process. The main goal of this study was to characterize the contaminated soil in terms of TPHs, BTEX, PAHs, and metals contents as well as microbiologically中国科学院土壤环境与污染修复实验室（南京土 Translate this pageThe combination of surfactant enhanced soil washing and degradation of nitrobenzene (NB) in effluent with persulfate was investigated to remediate NB contaminated soil
Polychlorinated Biphenylscontaminated Soil Translate this pagePolychlorinated Biphenylscontaminated Soil Washing with Mixed Surfactants Enhanced by Electrokinetics CHEN Tao, SUN Chengxun Surfactant, ElectrokineticsSoil Washing Potential of a Natural Surfactant Biodegradable natural surfactants obtained from plants can be an attractive alternative to synthetic surfactants in the remediation of contaminated soils. In this research, a plantbased surfactant obtained from the fruit pericarp of Sapindus mukurossi, a tree generally grown in tropical regions of Asia, is tested. A simple and economical method for the preparation of the surfactant is developed.
Effect of Ultrasound on SurfactantAided Soil WashingThe use of ultrasound as an enhancement mechanism in the surfactantaided soilwashing process was examined by conducting desoption tests of soils contaminated with naphthalene or dieseloil. The experiments were conducted to elucidate the effect of ultrasound on the mass transfer from soil to the aqueous phase using naphthalenecontaminated soil.Surfactant WikipediaChineseThe word surfactant is a blend of surfaceactive agent.. The United States National Library of Medicine's Medical Subject Headings (MeSH) vocabulary reserves surfactant for the meaning "pulmonary surfactant".For the more general meaning, surface active agent/s is the heading.Etymology and definition&ensp·&ensp

Evaluation of surfactant for flushing technique surfactantaided soilwashing technique for remediation of DDTcontaminant soil in the flowthrough system. Villa et al. (2010) investigated a coupled process soil washing with surfactant followed by photoFenton oxidation for remediation of a soil contaminated with DDT. Xia et al. (2012)Remediation of Diesel Contaminated Soils Using surfactant solution. (Taylor et al ., 2001). Soil washing using surfactants was innovated for soils contaminated with oil hydrocarbons. Clay content of the soil is a significant factor in washing because interfacial tension of the surfactant and clay will decrease surfactant

In most cases, while the soil can be remediated the contaminant itself cannot be reclaimed. However, ex situ soil washing with an aqueous solution of a surfactant would allow easy recovery of the conta

In typical soil washing operations using conventional surfactants, the wash mixture (emulsified oil in water) is generally sent for further treatment, including by aeration, filtration, adsorption using activated carbon, reverse
Comparison of a plant based natural surfactant with SDS Comparison of a plant based natural surfactant with SDS for washing of As(V) from Fe rich soil Soumyadeep Mukhopadhyay1, Mohd.

Department of Chemical Engineering, University ofSoil Washing Penn State College of Earth and Mineral Soil washing does not clean the soil, it separates the contaminated fraction from the clean fraction, hence minimizing the amount of soil need to be cleaned. It is a technique of concentrating contaminants through separation Soil washing does not destroy or immobilize the contaminants
