“…In this context, the low selectivity of the pollutants from the water necessitates a secondary separation process, which increases the costs and times of removing the oil spilled from the water's surface 7 . Conventional oil sorbents (e.g., synthetic, mineral, and vegetable materials) are characterized by a low oil/water selectivity and low oil‐sorption capacity 8–10 …”

“…7 Conventional oil sorbents (e.g., synthetic, mineral, and vegetable materials) are characterized by a low oil/water selectivity and low oil-sorption capacity. [8][9][10] Recently, due to their macroporous structure, flexibility, and low cost, porous materials such as foams have been identified as promising candidates for spill oil clean-up. 6 In addition, the foams show suitable mechanical properties in terms of elasticity and deformability.…”

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.

“…The ADL fiber morphology is made up of an irregular tube size. Like major natural fibers, the ADL fibers’ surface morphology is formed of several elementary fibers that are joined together throughout their length by pectin and other noncellulosic substances . Likewise, the fiber surface clearly shows some impurities.…”

Earlier research suggested using ash to substitute cement, whereas other studies looked at the possibility of using plant-derived agricultural wastes as fiber reinforcement in cement applications. This study offered an environmentally friendly option to change traditional mortars by replacing cement with fly bottom ash (FBA) waste at 10, 20, 30, and 40 wt %. Likewise, Arundo donax leaves (ADL) were employed to reinforce the modified cement mortars at 0.4, 2, 5, and 7 wt %. X-ray diffraction analysis of used materials was performed. The morphology of composites made with FBA and ADL was investigated using scanning electron microscopy. Moreover, the density, water uptake, thermal conductivity, energy gain, and carbon dioxide (CO2) emissions of the prepared composites were discussed. Their flexural strength, compressive strength, and displacement were also compared. Results revealed that the addition of FBA in the mortar matrix has a positive effect on decreasing the thermal conductivity and lightness of the mortar. In addition, 20 wt % of cement replacement by FBA guarantees simultaneously moderate mechanical properties, nearly 51% of energy gain, and 20% of total CO2 emission reduction. In the same, adding ADL to the 20wt %FBA mortar reduced the thermal conductivity and the lightness of the mortar. The 0.4 wt % ADL reinforcement ensured 59% energy gain and 6% of total CO2 emission reduction. A major amelioration was observed in the compressive strength (an increase of 14%) and in the plasticity (an increase of 27%) of the considered composite materials. In conclusion, using FBA as a cement replacement with low ADL content inclusion results in a thermal-resistant composite with reasonable durability and strength.

“…In particular, 300-2500 μm long fibers showed porous orthotropic morphology but distinct adsorption capacity to different pollutant viscosity. The result showed that the smaller these fibers were, the better oil uptake in high viscosity liquid that contained one kind of oil, such as kerosene, pump oil, virgin naphtha, and crude oil (Fiore et al 2019). The milkweed (Asclepias syriaca) floss had a superhydrophobic trait and hollow structure occupying 90% of its total volume.…”

Invasive plants as biosorbents for environmental remediation: a review

et al. 2022

Water contamination is an environmental burden for the next generations, calling for advanced methods such as adsorption to remove pollutants. For instance, unwanted biowaste and invasive plants can be converted into biosorbents for environmental remediation. This would partly solve the negative effects of invasive plants, estimated at 120 billion dollars in the USA.Here we review the distribution, impact, and use of invasive plants for water treatment, with emphasis on the preparation of biosorbents and removal of pollutants such as cadmium, lead, copper, zinc, nickel, mercury, chromate, synthetic dyes, and fossil fuels. Those biosorbents can remove 90-99% heavy metals from aqueous solutions. High adsorption capacities of 476.190 mg/g for synthetic dyes and 211 g/g for diesel oils have been observed. We also discuss the regeneration of these biosorbents.
