“…As shown in Fig. 3, comparison of the infrared spectrum confimed the extreme chemical similarity of cattail to reported kapok fibers (Likon et al, 2013): the broadest peak at 3363.1 cm −1 corresponds to the non-free O H stretching vibration (Wang et al, 2012). The strong peaks at 2925.3 cm −1 and 2846.7 cm −1 correspond to the asymmetric and symmetric aliphatic CH 2 and CH 3 stretching vibration, indicating the presence of plant wax which generally consists of long-chain alkanes, fatty acids, aldehydes, ketones, esters and alcohols (Abdullah et al, 2010).…”

“…Chemical composition of kapok and cotton fibers have been well investigated (Abdullah et al, 2010;Likon et al, 2013;Lim and Huang, 2007a,b;Wang et al, 2012). Similar to cotton fibers, kapok fibers typically comprise of 64% cellulose, 13% lignin and 23% Pentosan .…”

“…The limitations of synthetic materials are triggering an intensive interest in natural sorbents, since they are rich in nature, environmental friendly and costeffectively (Wahi et al, 2013). There are a large volume of published studies describing oil removal by various natural materials including straw (Ibrahim et al, 2009;Ibrahim et al, 2010), sago waste (Ngaini et al, 2014), bagasse (Said et al, 2009), rice husk (Ali et al, 2012;Angelova et al, 2011), cotton (Singh et al, 2013), kapok (Abdullah et al, 2010;Lim and Huang, 2007a,b;Wang et al, 2012Wang et al, , 2013, milkwood , silk-floss fiber (Annunciado et al, 2005), populus seed fiber (Likon et al, 2013) etc. In their work, oil sorption performances of these materials were investigated in the form of loose fibers, which presumably caused collection of oil-saturated natural sorbents becoming difficult and meanwhile essay leakage of absorbed oil.…”

“…The results of SP are different from those of AP, which is attributed to the different rough surface of AP and SP. Moreover, Likon et al reported that extraction in hexane did not considerably affect the chemical composition and stability of the populus seed fibers (Likon, Remškar, Ducman, &Švegl, 2013). The results imply that the AP and SP can be reused and recycled for several times with the help of N-hexane extraction.…”

“…Despite of their advantages, many natural fibres have low hydrophobicity and low buoyancy, and therefore they are only suitable for oil removal in the absence of water [7]. In response, many studies have been conducted on methods to improve the efficiency of oil removal of natural sorbent by means of alkalisation [5], chloroform treatment [3,5,13], acetylation [2,14], salt treatment [3], surfactant treatment [6,15], combination of chemical-biotechnological treatment [16], and esterification [8,17]. These studies show that appropriate chemical modification of natural sorbent could improve oil removal efficiency.…”

Esterification is one of the widely used chemical modifications to increase oil removal efficiency of natural fibres [14,[17][18][19][20]. Many esterification studies on natural fibres via acetylation in the presence of acetic anhydride have been conducted [21]. The hydroxyl (-OH) group in rice, wheat, rye, barley straws, and poplar wood fibre has been successfully replaced with acetyl groups via acetylation [19] Acetylation of sugarcane bagasse with Nbromosuccinimide (NBS) as the catalyst affords oil sorption capacity of 13.5-20.2 g/g on machine oil [20]. Acetylated banana fibre gives high oil sorption capacity (18.12 g/g) for machine oil [18]. Acetylated cotton [2] and acetylated wheat straw [14] show the reduction of the -OH group and the appearance of the three ester bands associated with successful acetylation at 1740-1745 cm À1 (C5 5O stretching of ester), 1369 cm À1 (C-H in -O(C5 5O)-CH 3 ), and 1234 cm À1 (C-O stretching of acetyl group attributed to C5 5O). However, the drawback in using acetic anhydride is the formation of acetic acid as by-product. Acetic acid causes residual smell, loss in material strength due to acidic hydrolysis of holocelullose, and metal fastener corrosion [21]. An interesting alternative in esterification of natural fibres is using fatty acid derivatives with water as a by-product [17]. Banerjee et al. studied on the esterification of sawdust using oleic acid, stearic acid, and decanoic acid in hexane with H 2 SO 4 as the catalyst, at 65 8C Sago or Metroxylon sagu, harvested in Sarawak, Malaysia, is a low-cost, natural adsorbent. The sago bark (SB) from M. sagu was investigated for adsorptive removal of emulsified oil in palm oil mill effluent (POME). Hydrophobicity of this sorbent in aqueous state was improved via esterification process. The esterification of SB was conducted at ratio of sago bark to stearic acid (SA) by 1:1, 4:1, and 7:1; percentage catalyst of 5, 10, and 15; and refluxing time 1, 4.5, and 8 h; respectively. These parameters were analysed using full central composite design (CCD) of response surface methodology (RSM). The adjusted R-squared value of 0.9509 showed that the regression model fit the data well. The predicted Rsquared value (0.9168) also indicated that the prediction of experimental data was satisfactory. Hydrophobicity test, FTIR, and SEM were carried out to characterise the esterified sago bark (ESB). Results showed that esterification process successfully increased the hydrophobicity of sago bark by 42.2% and oil removal efficiency in POME by 50.2%. A developed two-factor interaction (2FI) model showed that the preparation conditions of 1:1 SB:SA, 1...
