“…The other mechanism, 'solubilization', occurs above the CMC when contaminants are partitioned from the soil into the hydrophobic core of surfactant micelles (Deshpande et al, 1999). With these processes, a surfactant can increase the solubility of organic contaminants or lower the interfacial tension to enhance the mobility of the organic contaminants (West and Harwell, 1992 (Paria, 2008;Khalladi et al, 2009;Huguenot et al, 2015). However, even though the use of surfactants in the subsurface was originally developed in the petroleum recovery area to increase the amount of extracted crude oils from the subsurface, the feasibility of the surfactant usage for highly NAPL contaminated soils or aquifer having free products (TPH concentration > 100,000 mg/kg) has not been evaluated yet.…”

Batch experiments were performed to investigate the feasibility of a surfactant-enhanced soil washing process for soils heavily contaminated with crude oil in Kuwait. TPH concentration of the contaminated soil was 223,754 mg/kg, sampled from the bottom of a vaporized oil extraction pond in the Burgan reservoir field. Commercialized eight nonionic surfactants (Tween and Tergitol series) were used to measure the aqueous solubility for the crude oil. Among them, two Tergitol surfactants were used to evaluate the TPH removal efficiency of the surfactant-enhanced soil washing for heavily contaminated Kuwait soil. The solubility of the crude oil in surfactant solution was in the order Tergitol 15-S-7 > Tergitol 15-S-9 > Tergitol 15-S-12 > Tween-80 > Tween-20 > Tween-60, which showed that the crude oil solubilities of the Tergitol series were higher than those of the Tween series. The TPH removal efficiencies of 2% and 5% Tergitol 15-S-9 solution were 59% and 65%, respectively. Because the residual TPH concentration in the washed soil was still higher than the clean-up level (10,000 mg/kg), the soil washing process was repeated five times. After the fifth washing, the residual TPH concentration in the soil went down to 7,680 mg/kg and its removal efficiency was 97%.

“…Surfactants tend to remove the hydrophobic oil contaminants from soil either by solubilization or mobilisation . Good diesel removal efficiency have been accomplished by using nonionic surfactants like Tween‐80 . Aqueous foams are effective tools to improve the removal of non‐aqueous phase liquids (NAPLs) from contaminated soil.…”

Soils contaminated with diesel oil spilling from industrial areas, pipelines constitute a major environmental problem. This subsequently leads to the contamination of groundwater as well. Hence recently there is an increasing trend of usage of better techniques and agents that can perform diesel oil contaminated soil remediation with greater efficiency. The aim of this study is to report the potential, efficiency of using silica nanoparticle stabilized anionic surfactant foams for diesel contaminated soil remediation and also the different characteristics of the foam produced. Also comparison in terms of soil remediation efficiency using surfactant dispersions only were performed. The foams were produced from dispersions comprising of ethanol, anionic surfactant sodium lauryl sulfate (SLS) and silica nanoparticles, both hydrophobic and hydrophilic. The foamability and stability of the different foams were determined using the Dynamic Foam Analyzer DFA 100 (Kruss GmbH, Germany). The surfactant foams generated were then applied to the contaminated soil using a fabricated column. The results showed the gradual stabilization of the SLS foams by the use of the silica nanoparticles. The maximum diesel oil removal efficiency obtained by applying foam stabilized with 0.3 wt% hydrophobic silica nanoparticle, 10 vol% ethanol, 0.1 vol% SLS was 94.5%. The 0.3 wt% hydrophobic silica nanoparticle, 10 vol% ethanol, 0.1 vol% SLS surfactant solution showed only 61.5% maximum oil removal efficiency.

“…On the other hand, the methylglycinediacetic acid (MGDA) is a relatively novel chelate, much more biodegradable than others jointly with the essential advantage of having a stable thermal behaviour under a wide range of temperatures [35]. Likewise, surfactants with low toxicity and favourable biodegradability, such as Polyoxyethylene (20) sorbitan monooleate, also known as Tween ® 80 [36,37], have been extensively used in organic and inorganic contaminant removal treatments [11,38,39].…”

AbstractThe aim of this work was to investigate Hg removal ability of a novel microwave heating (MWH) treatment for marine sediment remediation enhanced by the application of several agents, biodegradable complexing agent (methylglycinediacetic acid, MGDA), surfactant (Tween ® 80), and citric acid. Main results revealed that MWH allowed a very rapid heating (~450 °C in 7 min) of the irradiated medium. However, without the addition of enhancing agents, a maximum Hg removal of ~72% can be achieved. The application of MGDA led to a higher contaminant removal of ~87% (residual concentration = 5.4 mg kg -1 ). For the treatment including the simultaneous addition of both chelating agent and surfactant, their synergetic action and stripping processes resulted in a very high Hg removal of ~99% for an irradiation time of 7 min, corresponding to a residual concentration of 0.56 mg kg -1 , which is lower than the Italian regulatory limit of 1 mg kg -1 . The use of citric acid resulted in a shortening of the removal kinetics, which allowed the successful application of a shorter remediation time of 5 min. The observed strong passive ability of sediments to convert a microwave irradiation energy into a rapid and large temperature increase undoubtedly represents a key factor in the whole remediation process, making the studied treatment an excellent choice. Kinetic data are suitable for a preliminarily assessment of the effectiveness of clean-up activities, and as basis for future scaling-up studies on MWH of Hgcontaminated sediments.
