“…The sorptive capacity defined for oil-burning products is 450–500% m/m (Wong et al 2016). In individual studies, broadleaf cattail seeds mercerised with NaOH (N, Na) have shown a sorptive capacity of 300–770%, which was the lowest value; the highest value was noted for the W and G seeds (2495–2661%).…”

“…Their sorptivity is quite considerable and often exceeds 100 g of an oil-related product in proportion to 1 g of sorbent (1000%). Furthermore, they can be neutralised in combustion plants for dangerous wastes, thus providing the opportunity to regain energy (Wong et al 2016). Still, other authors pay attention to another option—desorption.…”

Sorption of oil-related products (including mainly the propellants) is the very basic process that counteracts spreading these types of pollution into environment. Plenty of synthetic substances (including the monoaromatic hydrocarbons) are both from the surface and underground waters. The aim of this study was to present the research’s results on the possibilities of using the broadleaf cattail (Typha latifolia L.) seeds as a sorbent of monoaromatic hydrocarbons from an aqueous solution. In order to increase sorptive capacity, the seeds biomass was submitted for the process of mercerizing in diversified time and temperature in water and the NaOH solution. The removal of benzene, toluene, ethylbenzene, o-xylene, m-xylene and cumene was carried out by means of the “batch method”. All the conducted experiments have shown a high sorption level of the analysed pollutions from an aqueous solution. The best sorptive qualities appeared in the seeds drenched in 80 °C water for 4 h (W) 97 g/kg, what was 9.06% more absorbed hydrocarbons in comparison to the control sample (C) and 26.8% more than the smallest seeds drenched in NaOH for 240 min. in the temperature of 80 °C (N). The process of the seeds mercerizing that was conducted with the use of hot water appeared to be most effective, but seeds without mercerisation (C) is actually the material which absorbs the least amounts of energy for preparation and had quite good sorption capacity too.

“…However, it was observed that though alkaline treatment sample gave the highest adsorption capacity than hot water treated sample, the reverse was observed with the percentage of oil removed. This may be caused by higher weight gain from the adsorption of water molecules rather than crude oil after the adsorption process [19]. Similarly, the rise in percentage of oil removed observed in hot water treated sample can be attributed to its increase in floating ability.…”

A projection is thus inferred that by modifying the fibre structure through pretreatment, this will lead to modification in the fiber surface structure as well as to alteration in the surface energy, and possibly, an improvement in the adsorption ability for crude oil would be obtained [16] [19].…”

This study determined the adsorption ability of modified sponge gourd fibre in adsorbing crude oil from simulated oil-water mixture. Modification was done on the adsorbent by treating with hot water and sodium hydroxide. The dependence of the adsorption process on particle size of the fibre was determined using mesh sizes of 4.75, 2.36, 1.18 and 0.85 mm. The hot water treatment significantly increased the adsorbing ability of the sponge gourd, removing 83.3% of the crude oil from the mixture, alkaline treated sample removed 45.1% and the raw sample removed 22.9%. The result of the SEM images shows that hot water treated sample has more pores on the surface which influenced the better performance. The FTIR results obtained after the adsorption show the successful adsorption of crude oil on to the surface of the sponge gourd due to the presence of functional groups characteristics of groups found in crude oil. An optimum particle size for the sponge gourd was found to exist at the value of 1.18 mm, above and below which the crude oil removed was reduced. The modification of sponge gourd promoted the adsorption capacity for crude oil.

“…Because of this property, 1 g of unmodified sorbent absorbed high amount of water -14.54 g. Mercerization of the sorbent decreased water absorption by almost 7%. Researchers have treated cellulose fibers with alkali in different concentrations and even at low NaOH concentrations fibres can fibrillate, resulting in a reduced fibre diameter which causes a decrease of the surface area (Wong, McGowan, Bajwa, & Bajwa, 2016). The effect of alkali on the cellulose component of fiber causes swelling; therefore, the natural crystalline structure of the cellulose I relaxes.…”

Among the existing techniques for the removal of oil from water, the use of sorbents is generally considered to be one of the most efficient. Hydrophobicity (oleophilicity) is one of the major determinants of sorbents’ properties influencing the effectiveness of oil sorption in the presence of water. In order to improve these properties, the surface of the sorbent is modified using chemical or physical treatment methods. The purpose of this study is to analyse sorbent modification methods in order to increase their hydrophobic-oleophilic characteristics for the clean-up of oil spills taking into account environmental aspects. In this research a natural organic sorbent – moss – was treated with hot water (80 °C and 100 °C), mercerized, coated with oil and oil in water emulsions with concentrations at 10% and 50%. The test of water sorption capacity was performed to compare the hydrophobic properties of modified sorbents. The results of this research demonstrate the potential of natural organic sorbents in oil spill abatement. Hot water and alkali treatments can alter the surface characteristics of plant fibers and improve absorption capacity. Sorbent coating with plant triglycerides in low concentrations of oil can be applied in order to use the modified sorbent in areas where oil is spilled into the water in small amounts due to increased water resistance and lower product absorption properties. Treating water in 80 °C can be chosen for economic purposes. Sorbents treated this way could be used to clean oil spillages not from the water surfaces, but from soil and other solid surfaces.
