“…55 Foams constituted by large porosity (and consequently identifiable as a low-density foam) are usually characterized by higher and kinetically faster oil sorption. 56 Relating Figure 3 and, all the foams studied have a predominant hydrophobic character, as confirmed by the lower water absorption capacity than other oils for all batches. Furthermore, all samples show an oleophilic behavior, well-suited mainly in light oils.…”

Due to the enormous use of oil worldwide, accidental spills occur relatively often, threatening sea ecosystem. A remediation strategy, usually, includes materials of macroporous structure, flexibility, and low cost. Furthermore, they need to have oleophilic and hydrophobic characteristics. All these demands fulfill siloxane matrix foams. The addition of a natural zeolite, clinoptilolite, as filler, can improve their sorption characteristics and reusability. Silicone composite foams at different clinoptilolite content (35, 40, and 45 wt%) have been structurally characterized and evaluated by determining the sorption capacity in several liquids (naphtha, kerosene, pump oil, and water). The squeezing efficiency tests were performed to estimate the foams reusability. Compared with the unfilled one, the clinoptilolite filled foams shown lower sorption capacities with very high oil/water selectivity. The squeezing capacity of the foam with 40 wt% of clinoptilolite is equal to the unfilled foam for pump oil. In contrast, the squeezing capacity of 35 wt% clinoptilolite filled foam for naphtha oil is even higher. Compared to the foams, filled with other types of filler, the high effective oil selectivity of the foam with 35 wt% of clinoptilolite was proven, implying its superior suitability for light and heavy oils sorption.

“…evidenced that the bubble interconnection in the sorbent foam has a significant role in the sorption performance in oil spilling. Moreover high porous foams (and consequently low density foams) favor a higher and faster sorption of oils . In fact CNT_F36, which presents the largest pore size (2.0 mm) and a density similar with the CNT_F22 foam, shows a higher absorption capacity, at saturation in crude oil and in pump oil, respectively, 1830 mg g −1 and 97 mg g −1 .…”

According to the remark that an increase in sorbent density leads also to a slight reduction in sorption capacity in viscous oil, cell diameter increases at decreasing sorbent foam density facilitating the sorption of the pollutant in free spaces in the foam . However, on the other hand, the increase in pore radius causes oil release during the sorbent removal from the oil tank reducing consequently the retention action of the foam .…”

Sorption kinetics of pollutant oils, such as kerosene, virgin naphtha, crude oil, and pump oil, into porous siloxanic foams filled with carbon nanotubes (CNTs) are investigated. Both, pristine and functionalized, CNTs are used as foam fillers. Among all, the foam filled with pristine CNT shows a poor affinity with water and high sorption rate in light oils, in which it achieves the highest absorption values (7991 mg g−1 after 660 s and 6685 mg g−1 after 420 s, respectively, in virgin naphtha and kerosene). The kinetic data are described by the pseudo‐first order, pseudo‐second order, Elovich and intraparticle diffusion models. Results show that chemisorption processes are rate limiting the sorption step. In fact, pseudo‐second order model better represents the equilibrium isotherm data. © 2018 Wiley Periodicals, Inc. J.

“…However, their significant disadvantages such as brittle, lack of elasticity, ease of corrosion in acid/base environment, unable to be reused, and difficulty in surface modification restrict the application in oily wastewater treatment. Recently, polymer-based three-dimensional porous materials (3D-PMs) (such as sponge [46,47,48], foam [49,50,51,52], and aerogel [53,54,55]) with multi-layered network structure, higher porosity, adsorption capability, long penetration channel, and tunable pore structure are regarded as promising alternates for effectively oil/water separation after being functionalized with special wettability [56,57,58,59,60]. This is because polymers are always light in weight, ease of processability, resistance to corrosion, chemical stability, and the abundant functional groups on the surface which can be modified with a variety of materials easily [53,61,62,63,64,65].…”

Superwetting Polymeric Three Dimensional (3D) Porous Materials for Oil/Water Separation: A Review

2019

View full text Add to dashboard Cite

Oil spills and the emission of oily wastewater have triggered serious water pollution and environment problems. Effectively separating oil and water is a world-wide challenge and extensive efforts have been made to solve this issue. Interfacial super-wetting separation materials e.g., sponge, foams, and aerogels with high porosity tunable pore structures, are regarded as effective media to selectively remove oil and water. This review article reports the latest progress of polymeric three dimensional porous materials (3D-PMs) with super wettability to separate oil/water mixtures. The theories on developing super-wetting porous surfaces and the effects of wettability on oil/water separation have been discussed. The typical 3D porous structures (e.g., sponge, foam, and aerogel), commonly used polymers, and the most reported techniques involved in developing desired porous networks have been reviewed. The performances of 3D-PMs such as oil/water separation efficiency, elasticity, and mechanical stability are discussed. Additionally, the current challenges in the fabrication and long-term operation of super-wetting 3D-PMs in oil/water separation have also been introduced.
