“…Cai et al, 2019;Gorgulho et al, 2018;Hospodarova et al, 2018;Hu et al, 2019).After acetylation treatment, variations were observed in the couplings of characteristic bands; a reduction of the hydroxyl groups (O-H) occurs, which can be evidenced by decrease in absorption intensity in the reference band. Successful esterification can be confirmed by the behavior of three important absorption bands around 1736, 1367, and 1242 cm -1 , related to stretching vibration in carbonyl C = O, C -H, and C-O(Behnood et al, 2016;Gorgulho et al, 2018;Lopes et al, 2010b;Sun et al, 2004).…”

This work evaluates the adsorption capacity of the wild cane fiber (Gynerium Sagittatum) in crude oil. Both untreated biomass and treated with ionic liquid [2HEA][Ac] and acetylated were studied for oil spill cleanup in aqueous environment. Crude oil adsorption tests were performed in a thermostatic bath, varying the time for the kinetic study and the amount of oil for isotherm model. Kinetic study of oil adsorption allowed us to identify that the untreated fiber reached saturation in 90 minutes, while the fiber treated with acetylated and ionic liquid reached saturation in 30 minutes. In equilibrium, the total amount of oil adsorbed by the untreated fiber was 3.8g, whereas in acetylated and ionic liquid treated fiber, the obtained maximum adsorption capacity was 4.4 and 3.7 g, respectively. The remediation process using wild cane fiber followed a second order kinetic rate and Sips and Toth isotherm models provided the best fit to experimental data.

“…Eq. has provided a description of the Elovich model (10) (Elovich and Larinov 1962): where: the initial bio-sorption rate in (mg/g.min) is α and the surface coverage β are linked to the extent and the activation energy of chemisorption in (g/mg).…”

“…Adsorption is the greatest way to make biosorption a practical technology that is more costeffective than conventional methods by employing waste from sustainable agricultural sources of raw materials (Rajakovic et al 2007). Numerous adsorbent substances, including hydrated cellulose, were utilized to extract and reduce the oil in the resulting oily water ( (Behnood et al 2016) the results shown a strong ability to extract the oil from oily water. as adsorbents media.…”

The sedge cane is a year-round natural plant that is regarded as one of the most significant grasses on the planet, and it usually causes major disposal concerns. As a result, employing sedge cane as a low-cost adsorbent to remove oil from produced water is helpful from both an economic and environmental standpoint. The response surface methodology is used to investigate the reaction optimization of oil removal using the sedge cane. The tests had three independent variables: adsorbent dosage, contact time, and temperature, as well as one response variable is (oil removal percent). According to the findings, the adsorbent dosage had the biggest impact on the percentage of oil removed. The findings predicted that employing sedge cane with 5 gm/L adsorbent dosage at 40 °C and 60 min contact time, the optimum condition for oil removal would be up to 95%. Fourier transforms infrared (FTIR) and scanning electron microscopy (SEM) were used to analyze the sedge cane. The results of the Langmuir, Freundlich, Toth, and Sips isotherm models were 0.9967, 0.4166, 0.956, and 0.9062, respectively. Compared to the other models, Langmuir model best characterized the adsorption process. The reaction's kinetics were most accurately characterized by the PFO kinetic equation with 0.9382 for PFO, 0.8147 for PSO, and 0.7888 for the Elovich model. Temperature effects on thermodynamic parameters were investigated. The results of the testing showed that sedge cane is an effective adsorbent for eliminating oil from contaminated water.

“…Bagasse comprises 44% cellulose, 27% hemicellulose, 13% lignin, and 16% others (Behnood et al, 2016). Cellulose is the primary component for LA synthesis, so the bagasse needs to be pretreated to remove undesired components.…”

The abundance of sugarcane bagasse, a by-product of sugarcane juice extraction in sugar factories, serves as an advantage of its potential for producing chemicals such as levulinic acid (LA). Levulinic acid contains carbonyl and carboxyl groups that can be utilized for many applications, such as pharmacies, cosmetics, and solvents. Bagasse hydrolysis into LA was preceded by alkalineacid pretreatment to separate cellulose from hemicellulose and lignin. This treatment could minimize the disturbance of these unwanted components, so that LA synthesis would be more optimal. Pretreated bagasse contained 82.64% cellulose, about two-fold from the non-pretreated one. It was hydrolyzed with hydrochloric acid (HCl), which acts as a catalyst (a Bronsted acid), at 150-170 o C, 0.1-1 M catalyst concentration, 1-10% solid-to-liquid (cellulose:catalyst-solution) ratio, and 0-200 minutes reaction time. The range of LA yield values obtained in the study were between 15-64.05%. The maximum LA yield was obtained at a temperature of 160 o C, 1 M catalyst concentration, and 1% solid-to-liquid ratio. The high LA yield indicates the importance of pretreatment supported by optimal conditions of synthetic reaction. The reaction route involved in hydrolysis was cellulose-glucose-levoglucosan (LG)-hydroxymethylfurfural (HMF)-LA. The result exhibits that temperature and catalyst concentration do not significantly affect the maximum potential LA yield. However, higher temperatures and catalyst concentration can accelerate the time to achieve the maximum potential LA yield. Meanwhile, the LA yield increases with a lower solidto-liquid ratio. In contrast to previous studies, this study evaluated the reaction model in a more precise way using combination of models, considering that the reaction occurs between solid and liquid. The heterogeneous reaction model, namely the shrinking core model (SCM) for cellulose conversion to glucose and the first-order homogeneous reaction model for glucose to LA reaction, give good fitting results. The more appropriate reaction model is expected to be the basis of scaleup process carried out for industry one day. The results of this research have the potential to be applied for various other biomass raw materials with some improvements based on their characteristics which can be studied in the future.
