“…According to R 2 values, the uptake of cationic MB dye on NaIO 4 -NC fits well with the PSO kinetic model. A similar result was previously reported for the uptake of MB on cellulose-based adsorbent Ma et al[63].3.6. Regeneration Test.Regeneration experiments were done to authenticate the reusability of the material for practical application in real systems.…”

The study was focused on the preparation and characterizations of sodium periodate-modified nanocellulose (NaIO4-NC) prepared from Eichhornia crassipes for the removal of cationic methylene blue (MB) dye from wastewater (WW). A chemical method was used for the preparation of NaIO4-NC. The prepared NaIO4-NC adsorbent was characterized by using X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscope (SEM), energy-dispersive X-ray (EDX), and Brunauer–Emmett–Teller (BET) instruments. Next, it was tested to the adsorption of MB dye from WW using batch experiments. The adsorption process was performed using Langmuir and Freundlich isotherm models with maximum adsorption efficiency (qmax) of 90.91 mg·g−1 and percent color removal of 78.1% at optimum 30 mg·L−1, 60 min., 1 g, and 8 values of initial concentration, contact time, adsorbent dose, and solution pH, respectively. Pseudo-second-order (PSO) kinetic model was well fitted for the adsorption of MB dye through the chemisorption process. The adsorption process was spontaneous and feasible from the thermodynamic study because the Gibbs free energy value was negative. After adsorption, the decreased values for physicochemical parameters of WW were observed in addition to the color removal. From the regeneration study, it is possible to conclude that NaIO4-NC adsorbent was recyclable and reused as MB dye adsorption for 13 successive cycles without significant efficient loss.

“…In sub-summary, recently, the improvements in dyes adsorbents by cellulose aerogel have been widely published, but it is mainly functionalized with high-purity sources in terms of nanofibrils [60,67], carboxylated cellulose nanofibers [70], and microcrystalline cellulose [72], or industrial waste as cotton [68,69], new-paper [73]. The potentialities of modified-cellulose aerogel by agricultural byproducts such as coir, pineapple leaves, rice straw/husk, and bamboo would be extensively researched.…”

“…The highest removal rate of MB of robust cellulose sponge was attained 99.92 % at pH solution of 11, but the removal rate of CV was lower (92.74%). This difference was due to the large hindrance of bulky CV size, which reduced the adsorption capacity [69]. In summary, the contaminated adsorptions by cellulose aerogel may be performed over a wide pH range.…”

Water pollution caused by inorganic and organic compounds affects seriously health risks and the destruction of the water balance of the ecosystem. Water remediation is one of the greatest challenges of the modern age, which is faced by several countries in over the world. Many advanced technologies have been developed in recent years to manage this alarming problem. One of the recent research directions is to utilize agricultural waste, which is an abundant, low-cost, eco-friendly source, to manufacture cellulose aerogels for the removal of heavy metals, dyes, and oils from contaminated water. This review paper focuses on the latest green fabrication of bio-aerogels from various cellulose-based plant waste and studies on the kinetics and influence of factors such as contact time, pH solution, initial concentration, and temperature on the adsorption process to better understand the mechanisms of water treatment by the cellulose aerogels. Based on the discussion and summary, the potential of agro-waste sources in their value-added chain by developing efficient water treatment cellulose aerogels is comprehensively overviewed.

“…[23,24] In line with the similar concept, cellulose-based porous/ structures can also be considered for the same purpose even though it is still at a research stage. [25,26] Qin et al [25] reported different methods of making nano fibrillated cellulose (NFC)-based porous/foam structure. Cellulosebased wet foam usually shows instability because of its inability to provide surfactant type characteristics which are crucial to stabilize air bubbles to produce stable foam.…”

An ecofriendly and biodegradable porous structure was prepared from drying aqueous foams based on nano fibrillated cellulose (NFC), extracted from softwood pulp by subcritical water/CO 2 treatment (SC-NFC). The primary aim of this work was to use the modified SC-NFC as stabilizer for a water-based Pickering emulsion which upon drying, yielded porous cellulosic materials, a good dye adsorbent. In order to exploit the carboxymethylated SC-NFC (CMSC-NFC, with a degree of substitution of 0.35 and a charge density of 649 μeqv/g) as a stabilizer for water-based Pickering emulsion in subsequent step, an optimized quantity of octyl amine (30 mg/g of SC-NFC) was added to make them partially hydrophobic. A series of dry foam structures were prepared by varying the concentrations of treated CMSC-NFCs and 4 wt% was found to be the optimum concentration to yield foam with high porosity (99%) and low density (0.038 g/cc) along with high compression strength (0.24 MPa), superior to the conventionally extracted NFC. The foams were applied to capture as high as 98% of methylene blue dyes, making them a potential green candidate for treating industrial effluent. In addition, the dye adsorption kinetics and isotherms were found to be well suited with second order kinetics and Langmuir isotherm models.
