“…In contrast, dispersants break down oil into smaller particles for its subsequent removal. The most commonly used absorbents include polypropylene, polyethylene, and polyurethane foams, although cellulosic materials and other natural materials, such as minerals, are also good sorbents (Deschamps et al 2003;Hubbe et al 2013). The oil sorption capacity (SC) of polypropylene is reported as 4.5 to 10 times its weight, and that of urethane polymer is reported as 34.4% (Adebajo et al 2003).…”

Most plant fibers are good sorbents of oil; however, synthetic sorbents have a much higher sorption capacity (SC) than plant fibers. This study evaluated the effect of fiber treatments, specifically hot-water treatment and mercerization, on the absorption characteristics of selected plant fibers. Five common plant fibers-corn residues, soybean residues, cotton burr and stem (CBS), cattail, and oak-were evaluated for their absorption characteristics in crude oil, motor oil, deionized (DO) water, and a 80:20 mix of DO water. The fiber treatments included ground fiber (control), hotwater treatment at 80 °C for 4 h and 125 °C for 4 h, mercerization at room temp for 48 h, and mercerization at 300 °C for 1 h. The absorption capacity (AC) varied with fiber type, absorption medium, and fiber treatment. Mercerization at 300 °C increased the water absorption of soybean residue up to 8 g/g. Mercerization at room temperature and the hot-water treatment at 125 °C increased the crude oil absorption capacity. After certain treatments, the crude oil absorption capacity of CBS and corn fibers increased over 5 g/g, and the motor oil absorption capacity of cattail, corn, and soybean also increased to 4 to 5 g/g.

“…Besides these, the use of sorbents for oil spill removal has the advantages of making the oil separation process in an economical, efficient, and environmental friendly way; however, the use of this approach during the cases where thick layers of floating oils needs to be removed still remains a challenge (which is ideal for use of a skimmer and density-based separation) (Hubbe et al 2013). In general, the sorbent materials synthesized from non-renewable petroleum based sources are widely used in floating booms for the containments assortment and for the collection of spilled oils.…”

aCoconut coir, an agricultural waste, was chemically modified using esterification by fatty acid chloride (oleoyl chloride and octanoate chloride) for oil spill removal purposes. The modified coir (coir-oleate and coir-octanoate) were characterized by spectroscopy, thermal studies, contact angle, and morphological studies. The modified coir exhibited an enhancement towards the hydrophobic property but a decreased thermal stability. The oil adsorption performance was tested using a batch adsorption system. The effect of sorbent dosage, oil concentration, and effect of adsorption time on the adsorption capacity of the modified coir were also studied. From the analysis, the long chain oleoyl chloride (C18) was shown to be a better modifier compared to octanoate chloride (C8). The isotherm study indicated that the oil adsorption fitted well to a Langmuir model rather than Freundlich model. From the kinetic study, the result revealed a good fit in pseudo-second order model for all samples studied. The study therefore suggests that esterified coconut coir can serve as a potential biomaterial for the adsorption of spilled oil during operational failures.

“…This is followed by the Langmuir isotherm in Figure 2 with a correlation coefficient (R 2 = 0.8058) for pyrene sorption onto clay. The sorption process showed a good fit to the Langmuir isotherm which suggests a finite adsorption capacity and energetically equivalent sites [9]. The adsorption capacity Qo (mg/g) and adsorption intensity n for pyrene were 0.286, 0.561 and 0.225 and 0.789 for clay and sandy soil, respectively.…”

The adsorption behaviour of pyrene using clay and sandy soil under ambient conditions is investigated in this study. Adsorption equilibrium isotherms and adsorption kinetics experiments were carried out in solutions of pyrene concentrations (50 -250 mg/l) by using clay and sandy soil as adsorbents. Adsorption models were used to predict the mechanisms involved. The adsorption kinetics data best fitted the pseudo-second order kinetic model. The isotherm model which best represented the data obtained was the Langmuir model. The adsorption from the aqueous solution was observed to be time dependent and equilibrium time was found to be 34 and 28 hours for clay and sandy soil, respectively. The rate of adsorption using the pseudo-second order rate expression for pyrene was 0.00088 and 0.00085 min − 1 for clay and sandy soil, respectively.
