“…Synthetic polymers including polyurethane foams, acrylic resins, polypropylene and polyester fibres are widely used sorbents at present [3]. Natural organic sorbents based on various fibres, e.g., wool, cotton, cattail, sisal, coir, sponge gourd, silk floss, kapok, milkweed, are attractive alternative to synthetic ones [1][2][3][4][5][6][7][8][9][10][11]. Due to their high sorption capacity, buoyancy, hydrophobicity, reusability, biodegradability, and availability, wool and woolbased products can be very effective sorbents to clean up the oil spills [7][8][9][10].…”

“…Oily water treatment using fibrous sorbents generally involves both adsorption onto the fibre surface and absorption inside the fibre [1][2][3][4]8,11]. Process performances, commonly expressed in terms of oil removal efficiency (%) and sorbent sorption capacity (g oil/g sorbent), depend on various process factors including sorbent and oil characteristics, sorbent dosage, initial oil concentration, contact time, oily water pH and temperature [1][2][3][4][5][6][7][8][9][10][11].…”

Removal of some pollutants (Basra, Azeri, and Rebco crude oils, diesel, gasoline, and 1/1 (w/w) diesel-gasoline mixture) from water by sorption using Romanian Merino wool as a natural sorbent was studied in this paper. Batch experiments were conducted at different levels of initial sorbent mass (1 and 3 g), oily water pH (5 and 10), and operating temperature (30 and 45 �C). The effects of these factors on wool sorption capacity were evaluated. The sorption capacity of more viscous fuels (crude oils), i.e., 4.13-21.87 g/g, increased with an increase in oily water pH and a decrease in initial sorbent mass and temperature. For less viscous pollutants (diesel, gasoline, and their mixture), the sorption capacity (3.32-9.19 g/g) increased with a decrease in sorbent mass, the effects of pH and temperature being negligible. Experimental results were processed according to a 2 3 factorial plan and regression equations between the process factors and sorption capacity were obtained. SEM analysis revealed that the removal process was governed by both adsorption and absorption mechanisms.

“…Similarly, the cellulosic fibers milkweed (Asciepias) and cotton were shown to sorb significantly higher amounts of crude oil than polypropylene fiber and polypropylene web (Choi and Cloud, 1992). Nduka et al, (2008), Paulauskieneet al, (2014) and Dong et al, (2015) reported good oil sorption capacity by goat hair, peat and cattail/kapok blend respectively.…”

Rice husk a low cost agricultural waste was assessed for its efficiency as an oil spill sorbent by comparing its oil (crude oil, diesel and kerosene) uptake with that of a standard conventional synthetic sorbent mat used in oil spill clean-up. The sorption process of crude oil, diesel and kerosene onto rice husk and the standard was studied using Langmuir, Freundlich, Elovich, Temkin and Dubinin-Radushkevich adsorption models while the sorption kinetics was studied using Lagergren pseudo-firstorder, pseudo-second-order, intraparticle diffusion and liquid film diffusion models. Suitable environmental applicability of both sorbents was also studied. The result of the study shows that rice husk sorbed3.30± 0.23g of crude oil, 2.50± 0.81 g of diesel and 1.95± 0.72g of kerosene per unit mass while the standard sorbed11.50± 0.54g of crude oil, 10.34± 0.77g of diesel and 8.20± 0.93g of kerosene per unit mass. About 2.46± 0.17g of sorbed crude oil, 1.60± 0.64g of sorbed diesel and 1.57± 0.11g of sorbedkerosene were recovered from a unit mass of rice husk, while, 9.67± 0.36g of sorbed crude oil, 8.40± 0.95g of sorbed diesel and 6.50± 0.49g of sorbed kerosene were recovered from a unit mass of synthetic sorbent mat. The amount of the sorbed oils retained by a unit mass of rice husk is about 0.84± 0.22g of crude oil (25 % of sorbed crude oil), 0.90± 0.97g of diesel (36 % of sorbed diesel), and 0.38± 0.90g of kerosene (20 % of sorbed kerosene), while, 1.83± 0.33g of crude oil (15 % of sorbed crude oil), 1.94± 0.97g of diesel (19 % of sorbed diesel) and 1.70± 0.89g of kerosene (20 % of sorbed kerosene) were retained by a unit mass of synthetic sorbent mat. The result of the study indicates that the standard is a better sorbent for oil removal than rice husk. Rice husk has the ability to retain sorbed oil which makes it a good sorbent when oil recovery is not required, but disposal. The sorption process for both sorbents follows the Langmuir isotherm. Intraparticle diffusion model and liquid film diffusion model were parts of the rate determining steps of the sorption process of the oils onto rice husk and the standard.

“…[3][4] Due to the disadvantages of being short, light, hard to collect, easily broken, etc., cattail fibers are not effectively and fully used which leads to a waste of the resources. [5][6] The morphological characteristics and basic properties of the fibers play important roles in their utilization, 7 i.e., the morphological characteristics directly determine the essential application aspect of a textile fiber, and the basic properties directly determine the processing and staining method of the fiber. At present, most research works in engineering relating to cattail fibers focus on oil absorption using the water-proof and oil-absorption characteristics of the wax attached to the surface of the cattail fiber.…”

To extend the applications of cattail fibers in the textile, engineering and apparel industry, the morphological structure and properties of cattail fibers were tested and analyzed. The morphology was examined with a scanning electron microscope (SEM) and an optical microscope. The results show that the cross-sections of the cattail fibers were in the shapes of "p" or "Y" or ">-<"; the fiber length and fineness were mainly in ranges of 2.25-10.65 mm and 10-15 μm, respectively; there were about 56 fibers in a cattail cluster. The moisture-regain rate and mass ratio of the resistor of cattail fibers were measured to be 7.57 % and 1012.5 W•g/cm 2. In this case, the composition of the cattail fiber was similar to that of the kapok fiber. In addition, its pH value was found to be 6.7, which is harmless to the human body and the pectin content of the cattail fibers was found to be 1.013 %, which is similar to the cotton fibers. Furthermore, the acid resistance of the cattail fibers is better than their alkali resistance. Keywords: cattail fiber, morphological structure, properties Avtorji prispevka so testirali in analizirali morfolo{ko strukturo in lastnosti rogoznih vlaken, da bi raz{irili njihovo uporabo v tekstilni industriji in in`enirstvu. Morfologijo vlaken so analizirali pod opti~nim in vrsti~nim elektronskim mikroskopom (SEM; angl.: Scanning Electron Microscope). Raziskave so pokazale, da so vlakna v preseku razli~nih oblik: "p"," Y " ali ">-<"; dol`ina vlaken je bila ve~inoma med 2,25 mm in 10,65 mm in debelina (premer) med 10 μm in 15 μm. V vsakem rogoznem svitku (stroku) je okoli 56 vlaken. Vsak strok se navla`i s pribli`no 7,57 % vode in ima specifi~no elektri~no upornost pribl. 1012,5 W•g/cm 2. Sestava njihovih vzorcev je bila podobna sestavi vlaken kapokovca. Poleg tega imajo vlakna pH vrednost 6,7, kar je ne{kodljivo za~love{ko telo. Izmerjena vsebnost pektina v rogoznih vlaknih je bila 1,013 %, kar je podobno kot v vlaknih bomba`a. Nadalje avtorji ugotavljajo, da je odpornost vlaken proti kislinam bolj{a kot njihova odpornost proti bazam. Klju~ne besede: rogozna vlakna, morfolo{ka struktura, lastnosti
