“…The presence of chloride ions indicated high seawater sorption by UNT CP. A previous absorption study reported that efficient absorption of diesel molecules into the surface and porous structures of CP was determined by the relative porous surface that had apparent macropores [27]. However, in this study, only qualitative observations were made using SEM and detailed data such as porosity measurement, pore volume distribution, diameters and surface area of CP are needed to verify the contribution of surface characteristics towards improving sorption efficiency.…”

“…Coconut husk (fibre) has previously exhibited a sustainable biosorbent for oil removal through various modifications. Even though it has a strong oil sorption capacity, it has a relatively high efficiency of water absorbed, which might be a major constraint in practical implementation [19,27,29,30,43]. CP pith/peat has therefore been overlooked for its oil sorption capabilities.…”

“…Lignocellulose holding a variety of reactive functional groups allows for extensive and rapid absorption of oil and water [26]. Additionally, coir fibre has been previously shown to perform crude oil absorption successfully [27,28]. The high content of lignin in CP allows it to be resistant to biological degradation and biodegradable, and it requires up to two decades to decompose completely due to its durability.…”

“…The high content of lignin in CP allows it to be resistant to biological degradation and biodegradable, and it requires up to two decades to decompose completely due to its durability. Pyrolysed activated carbon and chemically modified CP/CF have been demonstrated in the past in effective oil clean-up [19,20,27,[29][30][31]. However, such treatments are not eco-friendly, are hazardous and have a high cost.…”

Oil spill incidents are hazardous and have prolonged damage to the marine environment. Management and spill clean-up procedures are practical and rapid, with several shortcomings. Coco peat (CP) and coco fibre (CF) are refined from coconut waste, and their abundance makes them desirable for diesel spillage treatment. Using a filter-based system, the selectivity of coco peat sorbent was tested using CP, CF and peat-fibre mix (CPM). CP exhibited maximal diesel sorption capacity with minimal seawater uptake, thus being selected for further optimisation analysis. The heat treatment considerably improved the sorption capacity and efficiency of diesel absorbed by CP, as supported by FTIR and VPSEM–EDX analysis. Conventional one-factor-at-a-time (OFAT) examined the performance of diesel sorption by CP under varying parameters, namely temperature, time of heating, packing density and diesel concentration. The significant factors were statistically evaluated using response surface methodology (RSM) via Plackett–Burman design (PB) and central composite design (CCD). Three significant (p < 0.05) factors (time, packing density and diesel concentration) were identified by PB and further analysed for interactions among the parameters. CCD predicted efficiency of diesel absorbed at 59.92% (71.90 mL) (initial diesel concentration of 30% v/v) and the experimental model validated the design with 59.17% (71.00 mL) diesel sorbed at the optimised conditions of 14.1 min of heating (200 °C) with packing density of 0.08 g/cm3 and 30% (v/v) of diesel concentration. The performance of CP in RSM (59.17%) was better than that in OFAT (58.33%). The discoveries imply that natural sorbent materials such as CP in oil spill clean-up operations can be advantageous and environmentally feasible. This study also demonstrated the diesel-filter system as a pilot study for the prospective up-scale application of oil spills.

“…It is odorless, undergoes microbial decomposition, can be used as a charge and has a hydrophilic nature, has low density, is cheap, easily obtained, resistant to heat, moisture, and saltwater (124). Coconut fibers can float on the water's surface for a long time, making it proper to collect the spilled oil (125).…”

Oil is a crucial raw material, preferably transported by sea. Thus, spills frequently take place in the ocean. Several alternatives have already been investigated to combat these disasters. This paper discusses the possibility of using lignocellulosic fibers for environmental recovery via the sorption of oil spilled in accidents. The data search was performed using Google Scholar. The obtained results allowed the choice of four fibers: coconut, sisal, peat, and kapok. The retrieved reference numbers were 8.360, 6.360, 6.360, and 2.380 for coconut, sisal, peat, and kapok fibers. There was no period restriction. Ten papers with significant results were chosen, and their main results are presented here. All fibers are renewable, besides presenting low cost and excellent sorption capability compared to polypropylene (commercial material) equal to 6 to 10 g/g of oil per gram of the sorber.

The growing global economy resulted in an incessant increase in transportation and exploitation of oil. Hence, the oil spillage has been considered a serious threat to aquatic and terrestrial ecosystems. Therefore, water purification has been considered a major challenge around the world. There are numerous classical methods available for oil removal from water, but owing to multiple defects and disadvantages, research efforts have focused to find such adsorbents which can improve oil adsorption capability. Traditional adsorbent material typically applied in oil removal includes activated carbon, organoclays, wool, zeolites, etc. These materials suffer from several drawbacks such as low absorption capacity, non-selective absorption, and complicated reusability, whereas nano-adsorbents offer multiple advantages such as having multiple sorption sites, large surface area, short intra-particle diffusion distance, tuneable pore size, and ease of low-temperature modification. Multi-walled carbon nanotubes (MWCNTs) are extensively used adsorbent materials with a strong affinity for the removal of organic pollutants. The functionalization MWCNTs further increase the sorption capacity of adsorbents manifolds to remove organic materials. These nanocomposites are also compatible with green materials and considered environmentally friendly adsorbents. This review paper aims at providing an insight to understand the properties of the MWCNTs and their potential use to adsorb hydrocarbons from water. Moreover, the synthesis methods of those materials, their modification procedures including the functionalization with metal oxide nanoparticles, and applications are also discussed in detail.
