“…Sorption is a phenomenon that englobes two processes: absorption and adsorption, where factors like porosity, morphology, and functional properties of the material’s surface must be considered. 4,7–9,36,37 Porous sorbents as PUs have a promising perspective for this finality. 38–40…”

This study evaluates the efficiency of castor oil–based polyurethane foams for oil sorption S10 and S500, focusing on the influence of the pores’ size. Different foams were produced by varying the polyol: isocyanate ratio (1:0.3; 1:0.5; 1:1.0; 1:1.5; and 1:2.0). The physicochemical properties, morphology, density, and Hg porosity were determined. The sorption capacity was influenced by exposure time, oil viscosity, and concentration of the reagents, considering variations in the hydrophobicity, void content, and morphology. The results showed that the foam produced at an in the same mass proportion (PUC) has a higher sorption capacity in exposure time from 25 to 40 h due to higher void content and larger pore diameter size. It was observed that the lower viscosity of S10 diesel contributes to the higher sorption efficiency compared to S500 one. The Taguchi method corroborated the mentioned results, indicating a higher sorption trend by varying the reagent concentration and exposure times.

In this paper, the application of multiwalled carbon nanotubes (MWCNTs) based on metal oxide nanocomposites as adsorbents for the removal of hydrocarbons such as kerosene from water was investigated. Functionalized MWCNTs were obtained by chemical oxidation using concentrated sulfuric and nitric acids. V2O5, CeO2, and V2O5:CeO2 nanocomposites were prepared using the hydrothermal method followed by deposition of these oxides over MWCNTs. Individual and mixed metal oxides, fresh MWCNTs, and metal oxide nanoparticle-doped MWCNTs using different analysis techniques were characterized. XRD, TEM, SEM, EDX, AFM, Raman, TG/DTA, and BET techniques were used to determine the structure as well as chemical and morphological properties of the newly prepared adsorbents. Fresh MWCNTs, Ce/MWCNTs, V/MWCNTs, and V:Ce/MWCNTs were applied for the removal of kerosene from a model solution of water. GC analysis indicated that high kerosene removal efficiency (85%) and adsorption capacity (4270 mg/g) after 60 min of treatment were obtained over V:Ce/MWCNTs in comparison with fresh MWCNTs, Ce/MWCNTs and V/MWCNTs. The kinetic data were analyzed using the pseudo-first order, pseudo-second order, and intra-particle diffusion rate equations.

“…[11][12][13] Another option for phase separation is the synthesis of floating sorbent materials, which have been used for the capture of oil-spills. [14][15][16][17] Recently, the technique has been applied by employing grafted hollow glass microspheres as floating sorbents. 18 On the other hand, the lifetime of plastic products is very short (about 40% have a duration of life less than 1 month), and this creates serious environmental problems.…”

BACKGROUND:The large production of polymeric materials worldwide and the difficulty of their decomposition make recycling necessary for both economic and environmental reasons. In this study, the separation of polyethylene terephthalate (PET) and polystyrene (PS) from ternary mixtures (polyethylene terephthalate/polystyrene/polypropylene, PET/PS/PP) and their subsequent utilization as sorbent materials was carried out. The carbonaceous sorbent materials based on polymeric matrices that were synthesized and characterized have low densities, resulting in ease of removal by flotation.RESULTS: Wetting agents polyvinyl alcohol (PVA) and dodecylamine (DA) were used to selectively wet PET and PS, respectively, and the effect of the wetting agents' concentration and pH on the effectiveness of the separation were studied. The recovered polymers were then utilized to prepare carbon composite materials that were used to remove of a test dye, Reactive Black dye, from aqueous solutions. CONCLUSION: The results show effective dye removal (nearly 98%) for both composite materials. The sorbents may then be regenerated for further wastewater treatment.
