“…The study of other researchers compared this efficiency with the removal of light fraction oil product, namely, gasoline (94.27%) and heavy fraction oil product, namely, grease (95.67%). Other researchers (Li et al 2015) also investigated polyester, whose sorption capacity was equal to 6.89 g/g for diesel.…”

Surface wastewater pollution due to accidental runoff or release of oil or its products is a longstanding and common environmental problem. The aim of the study was to investigate the impact of concentrations of oil products (diesel) and suspended solids, the sorbent type, the water flow rate and the interfering factors (chlorides) on the dynamic sorption of diesel and to test regeneration of polypropylene after its use for sorption. The sorbents used for study included common wheat straw (Triticum aestivum), polypropylene and sorbents modified with hydrogen peroxide solution. Standard methods were used for the determination of the investigated parameters and an in-house procedure employing a gas chromatograph was used for the determination of diesel concentration. The following factors that impact the sorption of diesel were investigated during the study: diesel concentration, concentration of suspended solids; type of sorbent (common wheat straw (Triticum aestivum), wheat straw modified with hydrogen peroxide, and polypropylene), water flow rate; and influence of the interfering factors (chlorides). Filtration speed in the range of investigated speeds does not affect the efficiency of diesel removal. Removal efficiency does not depend on the concentration of diesel before the sorbent reaches its maximum sorption capacity. Filling containing 50% of polypropylene and 50% of wheat straw was used for the study. It was found that polypropylene and wheat straw do not remove chlorides and suspended solids from solution. The study found that the solution of hydrogen peroxide boosts the hydrophobic properties of common wheat straw, but does not affect the sorption of diesel. The recommended number of regenerations of polypropylene should be limited to two.

“…This class of materials, known as polymer nanocomposites, attracts a huge interest both in industry and in academia, because it leads to outstanding adsorption, catalytic, magnetic, and optoelectronic properties . In recent years, different sorbent materials have been developed to enhance their oil sorption capacities, such as various natural and man‐made fibrous materials: ie, cotton, cellulose acetate, polystyrene, polyurethane, polypropylene, polyester, and others. The fibrous‐porous sorbents are promising, to some extent, due to their high separation efficiency, low cost, rich sources, and non‐toxicity.…”

Oil spill accidents and oily wastewaters induce a negative impact to the environment and human health. Therefore, the developing of new sorbent materials to combat promptly such type of pollution is of great interest. In this work, poly(vinylidene fluoride) and polysulfone ultrathin fibers reinforced with Halloysite nanoclay and CoFe 2 O 4 were developed via electrospinning method as composite sorbent materials. Fibrous composites were characterized by scanning and transmission electron microscopy. The magnetic property and the wetting behavior were ascertained by magnetometric and contact angle measurements, respectively. Results showed that the morphology of fibers was homogeneous, and the inorganic particles were properly dispersed within the polymeric matrix. Finally, sorbents were tested for sorption of oily liquids.Produced materials revealed the sorption capacities ranging from 3.70 to 10.01 g/g for poly(vinylidene fluoride)-based composites, and from 15.69 to 28.21 g/g for polysulfone-based composites, depending on the nature of tested oil.

“…An excellent sorbent material should have hydrophobic and oleophilic properties, high oil sorption efficiency, long‐playing storage capacity (providing more time for transfer of crude oil), facile fabrication process, and low cost. However, traditional oil sorbents, including man‐made fibrous materials, porous carbon‐based materials, and synthetic materials, experience various problems like low oil/water separation efficiency, poor oil storage capacity (sorption capacities: 2–30 times, draining time: 10–120 s), complicated preparation process, and high materials cost . Therefore, it is imperative to search for a simple method to fabricate a type of span‐new material that could be used for cleaning up crude oil leakage, typically with inexpensive cost, facile fabrication process, and excellent oil cleanup properties.…”

Coiled Plant Tendril Bioinspired Fabrication of Helical Porous Microfibers for Crude Oil Cleanup

et al. 2017

Fabrication of the helical fibers with sheath/core structure comprising 3D interconnected porous polystyrene (PS) and ductile polyvinylidene fluoride is inspired by coiled plant tendril. The key innovation point applied in this study is to produce a helical porous system based on sheath/core structure that can come into being a huge storage space in the sorption process for crude oil. More importantly, the mechanical properties confirm to have a more excellent improvement than that of the initial PS fibers, which make it become a possible candidate for the large‐area sorption and reuse of crude oil from the ocean or industry. The bioinspired fabricating strategy opens a significant avenue between the coaxial electrospinning and crude oil contamination cleanup. It is also expected that the unique structure can make it a promising candidate for applications in energy conversion, tissue engineering, and intelligent devices.
