“…A similar tendency was reported by Gurgel et al [14,43] and Ramos et al [20] for the adsorption of Cu 2+ on succinylated cellulose (Cell 6) [14], succinylated sugarcane bagasse (SCB 2) [43] and sugarcane bagasse modi ed with trimellitic anhydride (STA) [20]. SCB 2 has a higher amount of carboxylic acid groups (6.0 mmol/g), but a higher pH PZC value (5.26) [47] than SBox [21]. As a result, SCB 2 only exhibited an adsorptive capacity for Cu 2+ ions from a pH value of 3.0. e pH PZC value of STA is 3.16 because this material possesses carboxylic acid groups according to the optimized procedure reported in a previous study by our research group [21].…”

“…SBox and Cox were characterized by FTIR spectroscopy and solid-state 13 C NMR spectroscopy, as described in our previous study by Martins et al [21]. e 13 C NMR spectrum of Cox indicated that the main product has carboxylic acid groups but that starting material (nonoxidized cellulose) is also still present in much smaller amounts.…”

“…e oxidation reaction of SB and Cel was performed using the procedure previously described by Martins et al [21]. In a typical methodology, 5.000 g of Cel or SB was weighed into a 250 mL Erlenmeyer ask and then 80.0 mL of H 3 PO 4 (85% wt.%) was added to the ask under agitation at 25°C.…”

Batch and continuous adsorption of Co2+ and Cu2+ from aqueous solutions by oxidized sugarcane bagasse (SBox) and oxidized cellulose (Cox) were investigated. The oxidation reaction of sugarcane bagasse and cellulose was made with a mixture of H3PO4‒NaNO2 to obtain SBox and Cox, with the introduction of high number of carboxylic acid functions, 4.5 and 4.8 mmol/g, respectively. The adsorption kinetics of Co2+ and Cu2+ on SBox and Cox were modeled using two models (pseudo-first-order and pseudo-second-order) and the rate-limiting step controlling the adsorption was evaluated by Boyd and intraparticle diffusion models. The Sips and Langmuir models better fitted the isotherms with values of maximum adsorption capacity Qmax of 0.68 and 0.37 mmol/g for Co2+ and 1.20 and 0.57 mmol/g for Cu2+ adsorption on Cox and SBox, respectively. The reuse of both spent adsorbents was evaluated. Adsorption of Cu2+ and Co2+ on SBox in continuous was evaluated using a 22 factorial design with spatial time and initial metal concentration as independent variables and Qmax and effective use of the bed as responses. The breakthrough curves were very well described by the Bohart–Adams original model and the Qmax values for Co2+ and Cu2+ were 0.22 and 0.55 mmol/g. SBox confirmed to be a promising biomaterial for application on a large scale.

Polyethylenimine‐modified sugarcane bagasse cellulose (SBCMP), as a new adsorbent, was synthesized by the reaction of polyethylenimine (PEI) with sugarcane bagasse cellulose and glutaraldehyde. The adsorption of Cu(II) by SBCMP was pH‐dependent, and the higher removal efficiency of Cu(II) appeared in the range of pH 3.0–6.0. The adsorption isothermal data fitted well with the Langmuir model, and the maximum adsorption capacity of SBCMP was up to 107.5 mg/g. The adsorption kinetics was best described by the pseudo‐second‐order kinetic. The adsorption of Cu(II) by SBCMP was unfavorable at high temperatures, and thermodynamic analyses implied that the adsorption of Cu(II) by SBCMP was an exothermic reaction. Fourier transform infrared spectroscopy (FT‐IR) combined with X‐ray photoelectron spectroscopy (XPS) revealed that Cu(II) adsorption on SBCMP mainly controlled by the nitrogen atoms of NH group in PEI. The results of regeneration cycles showed that SBCMP was suitable for reuse in the adsorption of Cu(II) from aqueous solution. These experimental results suggested that SBCMP is expected to be a new biomass adsorbent with high efficiency in removing Cu(II) from wastewater.

The treatment of dye wastewater is of great significance to environmental protection. In addition, corrugated boxes are the main materials used in express packaging in the Internet shopping era, and its recycling has great value for sustainable development. In this study, cellulose triacetate (CTA) was successfully synthesized from discarded corrugated boxes with iodine as catalyst. And the obtained CTA was prepared by the emulsion solvent evaporation method into porous CTA particles, which can be used as an adsorbent to remove the dye crystal violet (CV). The adsorption kinetic and adsorption isotherm models revealed that the adsorption process was a single‐layer adsorption process with equal adsorption sites. The removal efficiency (R) of the CV solution (40 mg/L) at about 50 min R reaching equilibrium and was over 98%. The estimated maximum adsorption capacities for CV reached 9.1116 mg g−1. This research provides a new idea for the preparation of low‐cost dye wastewater treatment materials.
