Soil, diesel fuel contaminated, surfactant

Surfactant Flooding of Diesel-Fuel-Contaminated Soil... 

Use of surfactants may prove to be a good technique for separating diesel fuel fit>m a soil as indicated in results obtained in preliminary screening tests (removal efficiencies up to 97%) and from results of other studies performed on laboratory-packed soil columns (removal efficiencies up to 8.6%), assuming flow through the bulk matrix. Results presented here using undisturbed, diesel-fuel-contaminated soil cores taken from a site indicate, however, that removal of diesel fuel from the soil flooded with surfactant solution was generally less than 1%. Low removal efficiencies in these soil...
