Abstract:
The effect on the survival of the yeast S. cerevisiae of mixtures of diesel fuel (summer variety) with four representatives of different classes of surfactants – cationic (cetyltrimethylammonium bromide), anionic (sodium dodecyl sulfate), nonionic (Tween-80) and polymeric (polyvinyl alcohol) – was studied. It was shown that diesel fuel and two representatives of the classes of anionic and cationic surfactants (sodium dodecyl sulfate and cetyltrimethylammonium bromide) in the mixture exhibited higher toxicity than when exposed individually. At the same time, the toxicity of diesel fuel mixed wi

Abstract:
This paper presents the results of laboratory studies of the influence of the size of compound micelles created by a mixture of anionic surfactants, received from low quality hydrocarbon raw materials, and nonionic surfactants on the efficiency of residual oil displacement from highly water-encroached beds. It has been proved that varying the anionic/nonionic surfactant proportion in the mixture influences considerably on the size of the micelles formed, their interfacial activity and efficiency in high-viscosity oil displacement.

Abstract:
An investigation involving the addition of surfactant to remediate cadmium-contaminated soils was performed to determine the optimal surfactant enhanced remediation system. Anionic (sodium dodecyl sulfate, SDS), nonionic (Triton X-100, TX100) and cationic (cetyltrimethylammonium bromide, CTAB) surfactants were used to elucidate the extraction efficiency of surfactant. EDTA and diphenylthiocarbazone (DPC) were also added to enhance the extraction efficiencies of surfactants. Moreover, the pH effect was examined to determine the optimal surfactant systems.

Abstract:
This paper presents a nonionic surfactant in the anionic surfactant pair (ternary mixture) that influences the hydrophobicity of the alkaline–surfactant–polymer (ASP) slug within low-salinity formation water, an environment that constrains optimal designs of the salinity gradient and phase types. The hydrophobicity effectively reduced the optimum salinity, but achieving as much by mixing various surfactants has been challenging. We conducted a phase behavior test and a coreflooding test, and the results prove the effectiveness of the nonionic surfactant in enlarging the chemical applicability

Abstract:
The effectiveness of four food-grade and two industrial surfactants to remove toluene or 1,2,4-trichlorobenzene added to an Iowa soil was evaluated in batch and column experiments. One of the anionic food-grade surfactants, disodium n-hexadecyl diphenyloxide disulfonate (Dowfax 8390), was more effective than the other surfactants in shaken batch experiments. The maximum recoveries of the added toluene (57%) or 1,2,4-trichlorobenzene (71%) were obtained with one surfactant wash plus two water rinses. Dowfax 8390 also yielded the highest recovery of toluene (75%) or 1,2,4-trichlorobenzene (83%)

The adsorption capacity on the interphase surfaces of solution / air and solution / mineral material of binary mixtures of anionic (alkylbenzenesulfonic acid and its sodium salt (ABSCNa)) and nonionic surfactants (Tween-80) was studied.

Abstract:
The widespread use of detergents has raised concern with regard to the environmental pollution caused by their active substances, which are biorefractory, toxic or persistent. Even though anionic and non-ionic surfactants often used in commercial detergents composition are reasonably degradable under aerobic conditions and not particularly toxic at low concentrations, high concentration of surfactants influenced the activated sludge activity and are harmful for the aquatic environment. In the literature, data on the biodegradability and/or ecotoxicity of a certain type of surfactant (anionic,

Application of surfactants in the remediation of polluted sites with dense nonaqueous phase liquid (DNAPL) still requires knowledge of partitioning between surfactants and pollutants in the organic and aqueous phases and the time necessary to reach this balance.

Adsorption of anionic sodium hexadecyl sulfate (SHS) and nonionic Triton X surfactants with different ethoxylation degree: TX-45, TX-100 and TX-300 from their individual and mixed aqueous solutions at the surface of thermally graphitized carbon black (CB) was studied. It was found that at low solution concentrations addition of the nonionic surfactant increases the amount of SHS adsorbed from SHS/Triton X mixtures compared to SHS amount adsorbed from its individual solution. These findings might be explained by decreasing in electrostatic repulsion between SHS ions due to inclusion of the mole
