“…As previously reported, a severe mass reduction is observed in the phase around 270–420 °C, which may be related to the depolymerization and decomposition of glucose units in cellulose [ 28 ]. The mass loss of 9.28% in the final stage (400–600 °C) is attributed to the decomposition of the aerogel cross-linked structure and further conversion to CO 2 and H 2 O [ 29 ]. The XRD patterns obtained for CaCO 3 @STA/PAM/TOCN are shown in Figure 2 c. CaCO 3 @STA/PAM/TOCN exhibits a typical cellulose II diffraction pattern, where the peaks at 2θ = 20.2° and 22.2° correspond to the (110) and (200) crystal planes, respectively [ 23 ].…”

The effective utilization of biomass and the purification of dye wastewater are urgent problems. In this study, a biomass aerogel (CaCO3@starch/polyacrylamide/TEMPO-oxidized nanocellulose, CaCO3@STA/PAM/TOCN) was prepared by combining nanocellulose with starch and introducing calcium carbonate nanoparticles, which exhibited a rich three-dimensional layered porous structure with a very light mass. Starch and nanocellulose can be grafted onto the molecular chain of acrylamide, while calcium carbonate nanopores can make the gel pore size uniform and have excellent swelling properties. Here, various factors affecting the adsorption behavior of this aerogel, such as pH, contact time, ambient temperature, and initial concentration, are investigated. From the kinetic data, it can be obtained that the adsorption process fits well with the pseudo-second-order. The Langmuir isotherm model can fit the equilibrium data well. The thermodynamic data also demonstrated the spontaneous and heat-absorbing properties of anionic and cationic dyes on CaCO3@STA/PAM/TOCN aerogels. The adsorption capacity of Congo red (CR) and methylene blue (MB) by CaCO3@STA/PAM/TOCN was 277.76 mg/g and 101.01 mg/g, respectively. Therefore, cellulose and starch-based aerogels can be considered promising adsorbents for the treatment of dye wastewater.

“…85 A double-cross-linked biohybrid aerogel bead biosorbent made from waste bamboo paper and CS (BHA-CS) was prepared by sequential physical and chemical cross-linking. 86 The resulting BHA-CS beads were applied to remove methylene blue (MB) and Congo red (CR) dyes in both single and binary systems. The MB and CR adsorption capacities of the BHA-CS beads increased with increasing adsorbent dosage, contact time, temperature, and initial dye concentration.…”

“…Compared with synthetic polymer-based aerogels, the natural-based ones (such as cellulose, chitosan, and sodium alginate) are particularly attractive because of their biodegradability, reproducibility and green preparation process [16]. Biohybrid aerogel prepared from TEMPO-oxidized cellulose and chitosan has a good performance on the adsorption of pollutants from wastewater because it can combine the advantages of cellulose and chitosan, including ample resources, renewability, and functional groups [17]. Physical cross-linking is a widely used method to produce biohybrid hydrogels via electrostatic attraction, hydrogen bonding, and hydrophobic interactions [18].…”

In this work, a novel nanocellulose/chitosan biohybrid aerogel (NCBA) bead adsorbent was successfully prepared from oxidized bamboo nanocellulose and chitosan to remove diclofenac sodium (DS) from wastewater. Fourier transform infrared spectroscopy, scanning electron microscopy, and X-ray photoelectron spectroscopy were used to characterize the preparation of NCBA bead adsorbent. The results demonstrated that the adsorption kinetics were well described by the pseudo-second-order model, and the adsorption isotherms were well fitted by the Sips isotherm model with the maximum adsorption capacity of 321.26 mg/g on DS, which is much higher than most of the previously reported works. The absorption mechanism was governed by electrostatic interaction and hydrogen bond interaction. Moreover, the resulting bead remained a high removal efficiency after 5 regeneration cycles. In summary, it had been proved that the aerogel bead was an efficient bio-sorbent for removing DS from aqueous solutions.
