“…Also, the sorption or oil removal capacity is highly dependent on the sorbate extract concentration. This is confirmed by the research of Rongsayamanont et al (2017), who indicated the stability of biosorbents (composed by lipopeptides, glycerol, and palm oil) at a pH media range of 4-10 (using substances such as deionized water, alkaline water at pH 9, methanol, ethanol, dimethyl sulfoxide, acetone, chloroform, and hexane, it pointed the sorption capacity of biomaterials in acidic and alkaline media) without losing the film stability [23]. It is important to remark that the addition of higher quantities of extract gives the materials a lower pH value [13].…”

Chitosan films were used to remove heavy oil from connate water, deionized water, and seawater. In this research, chitosan-starch films were modified with natural extracts from cranberry, blueberry, beetroot, pomegranate, oregano, pitaya, and grape. These biodegradable, low-cost, eco-friendly materials show an important oil sorption capacity from different water conditions. It was observed that the sorption capacity has a clear correlation with the extract type, quantity, and water pH. In order to understand the physical and chemical properties of the films, they were analyzed according to their apparent density, water content, solubility, and swelling degree by scanning electron microscopy (SEM), thermogravimetric analysis (TGA), gas chromatography-mass spectroscopy (GC-MS), and the determination of surface area using the Brunauer Emmett Teller (BET) method. The results indicate that chitosan-starch films modified with natural extracts can be successfully applied for environmental issues such as oil spill remedy.

“…As previously described in this review, the mixing rule is a robust tool useful in the case of surfactant mixtures. Characteristic Curvature values of the main available Bios are measured by many authors according to the HLD - NAC model and are reported elsewhere [ 84 , 202 , 203 , 204 , 205 , 206 , 207 , 208 , 209 ]. These Cc values are good starting points for fast quality control on Bios, then thanks to the mixing rule it is possible to quantitatively adjust Cc value by adding other surfactants [ 203 ].…”

Microemulsion Microstructure(s): A Tutorial Review

et al. 2020

Microemulsions are thermodynamically stable, transparent, isotropic single-phase mixtures of two immiscible liquids stabilized by surfactants (and possibly other compounds). The assortment of very different microstructures behind such a univocal macroscopic definition is presented together with the experimental approaches to their determination. This tutorial review includes a necessary overview of the microemulsion phase behavior including the effect of temperature and salinity and of the features of living polymerlike micelles and living networks. Once these key learning points have been acquired, the different theoretical models proposed to rationalize the microemulsion microstructures are reviewed. The focus is on the use of these models as a rationale for the formulation of microemulsions with suitable features. Finally, current achievements and challenges of the use of microemulsions are reviewed.

This study investigated the potential of the bacterium Stenotrophomonas maltophilia UCP 1601 to produce a new biomolecule with emulsifying properties by determining the hemolytic activity, obtaining a halo of 9 mm in blood agar. Fermentations were carried out in saline mineral medium supplemented with 10% waste soybean oil (WSO) and different concentrations of glucose, peptone, ZnCl2, and MgSO4, according to a 24 full-factorial design. The results showed that the best results were obtained in condition 6 (medium composed of 4% glucose, 1% peptone, 2.72% ZnCl2, and 2.46% MgSO4), with excellent high emulsification index of 82.74%, using burned motor oil. The emulsifying property of the biomolecule produced was confirmed by the emulsification index of 78.57, 54.07, and 58.62%, using soybean, corn, and diesel oils, respectively, and the stability at different values of pH, temperature, and NaCl concentrations. The yield of the produced bioemulsifier was 2.8 g/L, presenting an anionic character and polymeric nature (37.6% lipids, 28.2% proteins, and 14.7% carbohydrates), confirmed by FTIR. The new bioemulsifier demonstrated promising potential for bioremediation of hydrophobic contaminants in the environment, since it had the ability to reduce the viscosity of WSO and burned motor oil, as well as excellent dispersion capacity of the burned motor oil in water (69.94 cm2 of oil displacement area), and removing 71.7% of this petroleum derivative from sandy soil.
