“…Likewise, a substance such as chloroform [8] is not only hazardous but a probable carcinogen. For oil/water mixtures, excellent results of oil removal are obtained by utilizing the mechanical method [18], filtration system [9] and hybrid assembly [19,20,21] without even having to modify the kapok fibre. Therefore, taking everything into consideration which includes the cost, modification might not be feasible when the performance is not greatly enhanced.…”

This paper highlights the oil absorbing properties of natural and modified kapok fibres. The discussion is centred on the waxy layer and hydrophobic nature that translate the excellent oil removal performance of kapok fibre. A stirring had shown that the oil absorption by natural kapok could be greatly enhanced to over 200 g/g. For dispersed oil in wastewater, a depth filtrating system with rotatable and taper-shaped filter column with kapok fibre was reported to recover 32.3 g/g of the oils. Several modifications to boost the performance of kapok fibre as in acetylation, solvent treatment, fibre hybridization, assembly structure and design, etc. are identified and discussed to shed some light into future prospective in oil and emulsion removal. So far, all the studies have shown that kapok fibre and its modified counterparts are promising green oil absorbents. ARTICLE HISTORY

“…Analysis of the fiber under scanning electron microscope (SEM), reveals its very smooth surface without any ripple and no coarse structure on its surface. The smoothness of the surface can be attributed to the wax that is adhered on the fiber 4,24,26 . A single kapok fiber can be viewed as a cylindrical microtube with a nano-scaled wrinkle on its surface.…”

Kapok fiber is a light, cottony, pale yellow to brown fiber obtained from Kapok fruit. The fiber is characterized by a large, hollow lumen and is generally hydrophobic due to its waxy surface. The fiber is difficult to spun into thread and it is commonly used as filling in mattresses, pillows, stuffed toys and upholstery. Compared to other natural fiber, kapok’s use is limited in application. However, it is now gaining attention in the scientific community as an important material due to its outstanding properties. This review will provide a detailed overview on the structure, composition and morphology of kapok fiber. It will also discuss the recent researches conducted on kapok fiber including its application as adsorbent material, biocomposite, biotemplate, electrode material and others.

“…The ideal oil sorbents are likely to possess the features such as (i) high sorption capacity, (ii) hydrophobicity, (iii) high sorption rate, (iv) high retention capacity, (v) mechanical properties, (vi) reusability and (vii) sustainability and biodegradability. However, it is still a challenge to get ideal oil sorbents that could meet all the above criteria [4].…”

“…In recent years, considering the advantages of natural fibers, including low cost, biodegradability and reusability, the fibers such as kapok [4,10], cattail [11], cotton [12], banana [13], nettle [7–9], milk weed [14], jute [15], coir [16], poplar seed fiber [17], chitosan [18] and other various vegetable fibers have been investigated for the oil spill cleanup applications. It was also recommended that natural fibers of low cellulosic content cannot be simply degraded by cellulose degrading microbes [4]. Even though natural fibrous sorbents are cost-effective than most synthetic sorbents, one of the main drawbacks associated with these materials is their low oil sorption capacity.…”

In this study, an attempt was made to enhance the oil sorption capacity of nettle fibers by grafting of butyl acrylate. Box–Behnken experimental design was used to study the effect of parameters such as reaction time, reaction temperature and monomer concentration-to-fiber ratio on graft add-on (%) and oil sorption capacity. At 4-h reaction time, 70℃ temperature and 2% monomer concentration-to-fiber ratio, highest graft add-on (%) and oil sorption were attained. Maximum oil sorption capacity of grafted nettle was 36.60 g/g and 25.56 g/g against crude oil and vegetable oil, respectively. Grafted nettle fibers were also subjected to characterization by Fourier-transform infrared spectroscopy, scanning electron microscopy and contact angle tests. Reusability test results showed that grafted nettle exhibited better oil sorption capacity than unmodified nettle even after seven sorption–desorption cycles. It is also observed that the oil sorption capacity of grafted nettle was higher than that of commercial polypropylene material. Based on these results, it is concluded that functionalized nettle prepared by grafting technique can be a potential material for oil spill treatment.
