“…The wide application of surfactants in many industrial areas, agriculture, pharmacy, medicine and everyday life results from their ability to adsorb at the solid–liquid, solid–air and liquid–air interfaces and to form micelles in the bulk phase of the solutions [ 1 , 2 , 3 , 4 ]. Indeed, in practice the mixtures of the surfactants, rather than the individual ones, are used [ 4 , 5 , 6 , 7 ].…”

The studies on the adsorption properties and composition of the adsorbed monolayer at the water–air interface of the binary Kolliphor® ELP (ELP) and Kolliphor® RH 40 (RH40) mixtures based on the measurements of the surface tension (γLV) of their aqueous solution in the temperature range from 293 to 318 K were carried out. The γLV isotherms were described by the exponential function of the second order and the Szyszkowski equation as well as predicted by Fainerman and Miller equation. The obtained γLV isotherms were analyzed using the exponential function of the second order, the Szyszkowski, Fainerman and Miller as well as independent adsorption equations. The γLV isotherms were also used for determination of the Gibbs surface excess concentration of RH40, ELP and their mixture (Γ) at the water–air interface as well as the mixed monolayer composition. Based on Γ and the constant a in the Szyszkowski equation, the standard thermodynamic functions of adsorption were considered. From the consideration dealing with the γLV isotherms obtained by us, it results, among others, that these isotherms for the non-ideal solution of macromolecular surfactants mixture can be predicted using the Fainerman and Miller equation. From this consideration, it also results that a simple method proposed by us, based on the isotherms of RH40 and ELP, allows us to predict the composition of their mixed monolayer in the whole concentration range of RH40 and ELP in the bulk phase.

Herein, we describe a surfactant‐catalyzed green methodology for electrophilic substitution reaction of 6‐aminouracil derivatives with various aldehydes that were neither reported earlier nor produced using conventional routes. Optimized results show the importance of anionic surfactant (SDS) on the reaction between hydrophilic and hydrophobic compounds in aqueous medium. All synthesized compounds were characterized by various spectroscopic methods like FTIR, NMR, HRMS, and SC‐XRD. Furthermore, the surfactant remediation from the reaction mixture was done using graphene oxide (GO). The results from batch‐adsorption studies indicate prominent sorption of SDS onto the surface of GO with an adsorption efficiency of ~84.9 %. The SDS adsorbed onto GO were analyzed using UV‐vis, FT‐IR, Raman, and HRTEM analysis. Next, the synthesized compounds were screened for their potential anti‐SARS‐CoV2 activity due to their structural resemblance with pyrimidine analogs acting as anti‐viral agents. The in‐silico results indicate that the synthesized compounds exhibit the highest inhibitory activity towards RdRp with binding energy −9.55 kcal/mol. In contrast, Remdesivir showed only −6.45 kcal/mol. In addition, upon preliminary screening of the compounds for possible antimicrobial activity (antifungal and anti‐leishmanial), 4 bf showed moderately high inhibitory activity with IC50 values of 205.48 μM and 124.97 μM for fungal and leishmanial strains, respectively.

“…The hydrophobic end is generally a carbon chain consisting of 10-20 carbon atoms. and the hydrophilic end containing groups that are ionizable in water (Corona et al 2021). It was reported that approximately 15 million metric tons of surfactants are produced globally each year (Ramprasad and Philip 2016), The most produced are anionic surfactants, which accounted for about 60%, followed by nonionic, percentage of 30%, while cationic and amphoteric types represented about 10% together (Palmer and Hatley 2018).…”

Wastewater treatment has an important responsibility to react to changing consumer and industrial-produced wastes that pose environmental challenges. Surfactants are one of these emerging contaminants. They are of interest because of their increasingly ubiquitous domestic and industrial use and the difficulty their presence causes traditional treatment. Compared with other treatment technologies, adsorption is a promising approach due to its low cost and environmental friendliness. This paper reviews the hazards of surfactants, the removal effect and mechanism of surfactants by conventional activated carbon, mineral materials, Chitosan-based materials, carbon materials and agricultural waste, and also summarizes the classification of adsorbent regeneration. Finally, future perspectives on surfactants removal and exploitation of adsorbent are presented. Through a comprehensive review, we expect that this review will help the reader to more rationally select the appropriate adsorbent based on the removal mechanism.
