“…The highest adsorption of Fe, Zn and Mn were 1.466, 0.203 and 0.019 mg/g in a fixed bed column at pH of 6, 15 cm of bed height and 3 ml/min of flow rate, while residual oil was 100 mg/g at pH of 3 and same bed height and flow rate [141]. In another research, they used natural zeolite to extract residue oil from POME in batch mode and achieved 70% of residue oil removal efficiency with 50 min mixing time at pH of 3.0 [146]. Kutty and coworkers used microwave incinerated rice husk ash (MIRHA) as an adsorbent for the treatment of POME.…”

“…Thus, immediate action to prevent pollution by reducing the hazardous loading from oily wastewater is of great significance. Currently, there are several methods used to remove residual oil from wastewater, such as adsorption, oil pumping, in situ burning, bioremediation, flocculation, electrocoagulation, and flotation (Ngarmkam et al, 2011;Shavandi et al, 2012). Among these methods, the adsorption process is widely adopted in this area because of its complete collection and removal of oil.…”

Graphene oxide has been used as an adsorbent in wastewater treatment. However, the hydrophily and dispersibility in aqueous solution limit its practical application in environmental protection. In this paper, a novel, environmentally friendly adsorbent, chitosan and chitosan-graphene oxide aerogels with a diverse shape, large specific surface area, and unique porous structure were prepared by a freeze-drying method. The structure of the adsorbents was investigated using scanning electron microscopy, Fourier transform-infrared spectroscopy, and X-ray diffraction (XRD); the specific surface area and swelling capability were also characterized. In addition, removal of diesel oil from seawater by chitosan aerogel (CSAG) and chitosan-graphene oxide aerogel (AGGO-1 and AGGO-2) was studied and batch adsorption experiments were carried out as a function of different adsorbent dosages (0-6 g), contact time (0-120 minutes), pH (3-9), and initial concentrations of oil residue (3-30 g/L) to determine the optimum condition for the adsorption of residue oil from seawater. The results showed that the chitosan-graphene oxide aerogels were more effective to remove diesel oil from seawater compared with pure chitosan aerogel. A removal efficiency ≥ 95% of the chitosan-graphene oxide aerogels could be achieved easily at the initial concentrations of 20 g/L, which indicated that the chitosan-graphene oxide aerogels can be used to treat the industrial oil leakage or effluent in the natural water.

“…Non-biological methods have been reported for the treatment of mill effluent [8] such as adsorption [4,9], coagulation [5], air floatation [10], and membrane filtration [11]. Different oil sorbent materials from organic [2,12], inorganic minerals [13], and organic synthetic fibers [14] have been explored and these include chitosan [5], bentonite/ organoclay [15], zeolite [16], and superhydrophobic sponges [17]. However, the utilization of agricultural products such as barley straw [6], raw bagasse [18], rice husks [19], oil palm [20], and Ceiba pentandra [2,[21][22][23][24] has gained increasing attention due to its biodegradability and low cost.…”

A B S T R A C TThe performance of raw Ceiba pentandra (L.) Gaertn (raw kapok fibers (RKF)) for oil sorption and palm oil mill effluent (POME) treatment was compared with structurally modified kapok (NaOH-treated (SKF) and surface-modified kapok fiber (SMKF)) and bentonite clay. Based on FTIR, kapok wax functional group at 1726/cm was not detected in SKF rendering higher hydrophilicity. The reduction in peak intensity at 473 and 523/cm upon HCl treatment of bentonite, suggests the cleavage of Si-O-Al bond layer and Si-O-Mg (Fe) bonds. For filtration under gravity at 0.08 g/cm 3 , SKF showed high POME sorption of 82 g/g, but lower diesel sorption of 23 g/g. With HCl-treated bentonite, POME sorption at 69 g/g was only slightly higher than diesel sorption of 60 g/g. However, RKF and raw bentonite achieved higher removal efficiency of biological oxygen demand, chemical oxygen demand (COD), total organic carbon, and total nitrogen at 74-98% and 72-94%, respectively, than with SKF at 66-80%, and HCl-treated bentonite at 64-80%. In batch mode, SMKF at 0.08 g/ cm 3 showed the highest oil sorption capacity of 56.7 g/g for Crude Palm Oil (CPO) and 33.7 g/g for diesel. Under continuous mode with 4000 mg/l CPO in water, 99% of COD removal was achieved at all packing densities and flow rates, regardless of kapok packing material. The dynamic oil retention was 96-99% for CPO and 99-100% for diesel at all packing densities. RKF and SMKF can both be suitable sorbent materials for CPO and diesel sorption, and for POME treatment.
