“…At present, the reutilization of vegetable materials in the adsorption process represents a significant benefit not only from an economic point of view but also for environmental protection [ 17 , 38 , 39 ]. Taking into consideration these aspects, the following experiment was performed to evaluate the reutilization of maize stalk.…”

New research applications involving the use of cellulosic material derived from maize stalk for on-site treatment of leachate were evaluated for specific removal of Cu(II) and Fe(III) from real, highly polluted tailing pond and mine wastewater samples. Two major issues generated by anthropic mining activities were also tackled: wastewater metal content decrease to improve water quality and subsequently metal specific recovery, increasing the economic efficiency of metal production by using a green technology for residual management. Rapid saturation of the maize stalk mass determined in batch studies and the mine pilot experiment led to diminished metal concentrations in the second pilot experiment, where Cu(II) and Pb(II) from synthetic solutions were monitored in order to test biomaterial performances. In addition, in the second pilot experiment, maize stalk removed Pb(II) in the first 36 h, below the determination limit of the analytical method. The biomaterial bed in the column was saturated after 252 h of inflow solution. FTIR-ATR, TG and SEM techniques probed the interaction between maize stalk polar groups C=O, –OH, C–O and tailing water metallic ions by large FTIR band displacements, intensity decrease and shape changes, modification of thermal stability and by changes in the appearance of adsorbent microstructure images owing mainly to ion exchange mechanism.

“…The wood waste-derived SP-TAPI prepared under optimal conditions was used to treat the Cd(II)-containing wastewater. Considering the practical application of the adsorption process onto the wood fiber-based sorbents [12,20], the evaluation of all sorbents was based on the SP substrates (not involving PEI only). Thus, the effect of the different sorbents on the adsorption efficiency of Cd(II) was evaluated (Figure 4a); ~22.66 mg/g of removal capacity was achieved for the SP-TAPI-2.0, which was nearly 156-fold and 3-fold that of the pristine SP and SP-(TA-APTES), respectively.…”

“…Among the various treatment techniques, adsorption has become the major technique and has been extensively applied for the disposal of wastewater because it is low-cost, shows high efficiency, and is simple in design [9,10]. In recent years, sustainable sorbents prepared from renewable biomass such as cellulose and/or lignocellulose-based materials, chitosan, and alginate, have received increasing attention [11,12]. Among these biosorbents, lignocellulose is considered a promising and cheap biosorbent [13,14].…”

“…Vitas et al found that carboxylic acid functionalized wood could be used for the removal of copper(II) from water [20]. To date, most studies have focused on deriving wood-based sorbents from solid wood and nanocelluloses extracted from wood, and only limited efforts have been devoted to the direct use of wood waste as a lignocellulosic source [12,21]. Furthermore, most processing procedures involve the use of strong acids and have high-cost and energy waste, which impedes sustainable development [22,23].…”

The fabrication of functional lignocellulose-based materials has drawn considerable attention because it acts as a green separation/absorption material owing to its multi-porous mesostructure. In this study, a surface functionalized lignocellulose-based adsorbent for the highly efficient capture of Cd(II) ions was prepared through facile in situ co-deposition of wood waste-derived saw powder (SP) in the presence of tannic acid (TA) and aminopropyltriethoxysilane (APTES) mixed aqueous solution. The SP was first modified using TA-APTES coating to synthesize the functional SP substrate (SP-(TA-APTES)). The SP-(TA-APTES) hybrids served as reactive platforms, which enabled further decoration with amino-rich polyethylenimine (PEI) due to the outstanding secondary reactions of the TA-APTES layer. The surface morphology of the resulting SP-(TA-APTES)-PEI (SP-TAPI) composites were investigated using Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). Significantly, the combined advantages of the lignocellulosic skeleton, the layer-particle structure, and the hybrid coating contributed to the enhanced adsorption capacity of Cd(II) (up to 22.66 mg/g at pH = 5.0). This removal capacity was higher than that of most reported agricultural waste-based or lignocellulose-based materials. The Cd(II) adsorption mechanism of the surface-modified SP-TAPI composites was studied in detail. These results provide new insights into the high value-added utilization of agricultural waste for water purification applications.

“…When adsorption takes place at a temperature higher than equilibrium temperature, the desorption characteristics of the CBH molecules become dominant, owing to the excessive molecular motion that causes such a slight decrease of the adsorption capacity [ 46 ]. Furthermore, similar to adsorptive removal of dyes from wastewater, CBHs show higher adsorption capacity for the removal of metal ions through endothermic adsorption [ 185 ], while the adsorption capacity is significantly lower for exothermic adsorption [ 186 ].…”

Finding affordable and environment-friendly options to decontaminate wastewater generated with heavy metals and dyes to prevent the depletion of accessible freshwater resources is one of the indispensable challenges of the 21st century. Adsorption is yet to be the most effective and low-cost wastewater treatment method used for the removal of pollutants from wastewater, while naturally derived adsorbent materials have garnered tremendous attention. One promising example of such adsorbents is hydrogels (HGs), which constitute a three-dimensional polymeric network of hydrophilic groups that is highly capable of adsorbing a large quantity of metal ions and dyes from wastewater. Although HGs can also be prepared from synthetic polymers, natural polymers have improved environmental benignity. Recently, cellulose-based hydrogels (CBHs) have been extensively studied owing to their high abundance, biodegradability, non-toxicity, and excellent adsorption capacity. This review emphasizes different CBH adsorbents in the context of dyes and heavy metals removal from wastewater following diverse synthesis techniques and adsorption mechanisms. This study also summarizes various process parameters necessary to optimize adsorption capacity followed by future research directions.
