“…Activation, carbonization, grafting, chemical treatment, and composite production are the most prevalent modification processes [24]. Because of their economic feasibility, ease of synthesis, hetero-porous architectures, and high adsorption performance, carbon fibers synthesized from natural, low-cost, and abundant biomass are considered environmentally acceptable adsorbent materials [25].…”

Uranium (as a hazardous and radioactive element) removal from wastewater requires reliable technology and proper functional materials. Carbon fiber species that are produced from agricultural solid waste can be a proper type of low-cost adsorbents for wide uses in wastewater treatment. In this work, two carbon fiber species labeled CF-RH and CF-SCB were synthesized from two different agricultural wastes, namely, rice husk and sugarcane bagasse respectively. The structural properties of carbon fiber were verified by XRD, FTIR, and Raman, spectroscopy. Both nitrogen-adsorption–desorption BET surface area and TEM were performed to figure out the textural characteristics of the presented sorbents. The charges on surfaces of the fibers were detected via zeta potential analysis. The prepared carbon fibers were applied for uranium removal from aqueous solution by adsorption technique. The acquired data display that the equilibrium time was 240 min. The results of adsorption process are nicely fitted with pseudo-second-order-kinetic and Langmuir isotherm models. The maximum sorption capacity was 21.0 and 29.0 mg/g for CF-RH and CF-SCB, respectively. Sorption thermodynamics declare that adsorption of U(VI) is an endothermic, spontaneous, and feasible process. The picked findings of this study could emphasize high reliability of the introduced adsorbents in efficient tackling of water contaminants.

“…An increment in the b T values, which is related to the heat of sorption from 0.024 to 0.041 kJ/mol (Table 1 ) testified to slightly higher bonding probability of NB at elevated temperature (313 K). Further, the endothermic physisorption of NB was evidenced by the positive b T values below 8 kJ/mol, which is confirmed by the pertinent thermodynamic parameter (∆ H °) 82 .…”

In recent times, biopolymer-metal oxide nanocomposites have gained prominent importance in the attenuation of environmental toxicants from aqueous phase. But lanthanide oxide-based biopolymer nanocomposites have scantly been evaluated for their adsorption potential. A novel guar gum-polyacrylamide/erbium oxide nanocomposite (GG-PAAm/Er2O3 NC) adsorbent was synthesized by copolymerization of guar gum (GG) and acrylamide (AAm) utilizing N-N′-methylenebisacrylamide as a crosslinker and Er2O3 as a reinforcing agent. The adsorptive efficacy of GG-PAAm/Er2O3 nanocomposite was evaluated using nile blue (NB) as a model pollutant dye from aquatic system. The prepared adsorbent was characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) analysis, Brunauer–Emmett–Teller (BET) analysis, thermogravimetric analysis, scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM–EDX), and high-resolution transmission electron microscopy (HRTEM). The optimal process parameters, which include dosage (0.8 g/L), agitation time (40 min), initial solution pH (6), and initial NB concentration (80 mg/L) were determined by batch methodology. The equilibrium data for NB confiscation was better expressed by Langmuir isotherm model, with maximal adsorption effectiveness (Qm) of 225.88 mg NB/g demonstrating the actively monolayer adsorption onto homogeneous surface of GG-PAAm/Er2O3 NC. The kinetics of NB sorption process onto GG-PAAm/Er2O3 NC was reliable with pseudo-second order model. Thermodynamic parameters such as ΔH° (15–17 kJ/mol) and ΔS° (0.079–0.087 kJ/mol/K), and − ΔG° (8.81–10.55 kJ/mol) for NB validated the endothermic, an increased randomness at the GG-PAAm/Er2O3–NB interface, and spontaneity and feasibility of the process, respectively. The spent nanocomposite was effectively regenerated with NaOH, and could be reused proficiently for five runs demonstrating the high reusability potential of the nanocomposite. The commendable removal efficiency and high reusability of GG-PAAm/Er2O3 NC recommended it to be a highly competent adsorbent for cationic dyes particularly NB diminution from aqueous waste.

“…The FTIR spectral profiles recorded for HAP, BBC, BBC-HAP and BBC-HAP-Colorant are shown in Figure 3 c. The hydroxyl group in BBC or HAP is represented by the stretching vibration of the -OH group at 3416 cm −1 [ 38 , 39 ]. The band located at 1618 cm −1 was assigned to the −COO in CO 3 2− in HAP [ 40 ], and the 1560 cm −1 and 1170 cm −1 peaks observed in the spectrum profile for BBC are attributed to the stretching vibration of the C-C bond and C-O, respectively [ 41 , 42 , 43 ]. In addition, the HAP contains a P-O (V 3 ) band of 1034 cm −1 and O-P-O (V 4 ) bands of 603 cm −1 and 566 cm −1 [ 35 ].…”

The clarification of sugarcane juice is a crucial stage in the sugar manufacturing process, as it affects evaporator performance, sugar quality and yield. The emergence of environmentally friendly and efficient adsorption technology has resulted in widespread interest in carbon-based materials. However, their low adsorption capacity and reusability make them unsuitable for processing sugarcane juice. Here, we provide a cost-effective and sustainable method to dope hydroxyapatite (HAP) nanoparticles on porous carbon (BBC) derived from sugarcane bagasse (BBC-HAP). The composite shows excellent adsorption capacity for color extract from sugarcane juice of 313.33 mg/g, far more effective than the commercially available carbon-based adsorbents. Isotherm studies show that the adsorption of BBC-HAP composite to the colorants is a monolayer process. The pseudo-first-order (PFO) and pseudo-second-order (PSO) kinetic models demonstrate that the adsorption process is dominated by chemisorption and supplemented by physical adsorption.
