“…They observed that the optimal ratio between components alginate/starch/n-clay was 1/2/3 (dried components) with a maximum removal efficiency of 95% for Cu 2+ ions after 25 h of contact. The removal of Cu 2+ , Mg 2+ , Fe 2+ , and Pb 2+ by using alginate combined with different nanocellulose biosorbents was studied by Abou-Zeid et al [ 32 ]. They found that tri-carboxylate cellulose nanofibers (TPC-CNF) combined with alginate presented high removal efficiency for the metal ions studied with the best values obtained for Pb (95%) and Cu (92%), but a lower removal efficiency for Mg (54%) and Fe (43%).…”

“…Lagoa et al [ 22 ] discovered in their work that dried alginate beads are more adsorbent due to the higher surface area. Alginate functionalized with other materials, such as activated carbon [ 23 ], biochar from biomass [ 24 , 25 ], carbon nanotubes [ 26 ], graphene [ 15 ], and other biopolymers [ 27 , 28 ] have also proved to be efficient in the removal of metals such as Cd 2+ [ 29 , 30 ], Cu 2+ [ 23 , 31 ], Mg 2+ , Fe 2+ [ 32 ], Pb 2+ [ 23 , 31 ], and Zn 2+ [ 31 ].…”

Novel Adsorbent Based on Banana Peel Waste for Removal of Heavy Metal Ions from Synthetic Solutions

Due to its valuable compounds, food waste has been gaining attention in different applications, such as life quality and environment. Combined with circular economy requirements, a valorization method for waste, especially banana waste, was to convert them into adsorbents with advanced properties. The banana waste, after thermal treatment, was used with high removal performances (100%) for the removal of heavy metals, such as Cr, Cu, Pb, and Zn, but their small particle size makes them very hard to recover and reuse. For this reason, a biopolymeric matrix was used to incorporate the banana waste. The matrix was chosen for its remarkable properties, such as low cost, biodegradability, low carbon footprint, and reduced environmental impact. In this research, different types of materials (simple banana peel ash BPA and combined with biopolymeric matrix, ALG–BPA, CS–BPA) were prepared, characterized, and tested. The materials were characterized by means of attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), optical microscopy (OM), scanning electron microscopy (SEM), and tested for the removal of metal ions from synthetic solutions using atomic absorption spectroscopy (AAS). The ALG–BPA material proved to be the most efficient in the removal of heavy metal ions from synthetic solution, reaching even 100% metal removal for Cr, Fe, Pb, and Zn, while the CS-based materials were the least efficient, presenting the best values for Cr and Fe ions with a removal efficiency of 34.14% and 28.38%, respectively. By adding BPA to CS, the adsorption properties of the material were slightly improved, but also only for Cr and Fe ions, to 37.09% and 57.78%.

“…Generally, the affinity of native cellulose microfibers towards organic pollutants is 100 to 500 times lower than that of conventional nanomaterials, such as zeolite or activated carbon, due to the low number of active sites for interaction with the organic pollutants [107]. Alternatively, surface-modified nanocelluloses have been tested as support materials for the adsorption of various organic pollutants [39,[107][108][109][110][111][112][113][114][115][116][117][118][119][120][121][122][123][124]. This is mainly explained by their robust mechanical properties, the high specific surface area that allows creating active interaction sites after functionalization, and the small pore size of their filters/membranes.…”

Nanocelluloses are promising bio-nano-materials for use as water treatment materials in environmental protection and remediation. Over the past decades, they have been integrated via novel nanoengineering approaches for water treatment processes. This review aims at giving an overview of nanocellulose requirements concerning emerging nanotechnologies of waster treatments and purification, i.e., adsorption, absorption, flocculation, photocatalytic degradation, disinfection, antifouling, ultrafiltration, nanofiltration, and reverse osmosis. Firstly, the nanocellulose synthesis methods (mechanical, physical, chemical, and biological), unique properties (sizes, geometries, and surface chemistry) were presented and their use for capturing and removal of wastewater pollutants was explained. Secondly, different chemical modification approaches surface functionalization (with functional groups, polymers, and nanoparticles) for enhancing the surface chemistry of the nanocellulose for enabling the effective removal of specific pollutants (suspended particles, microorganisms, hazardous metals ions, organic dyes, drugs, pesticides fertilizers, and oils) were highlighted. Thirdly, new fabrication approaches (solution casting, thermal treatment, electrospinning, 3D printing) that integrated nanocelluloses (spherical nanoparticles, nanowhiskers, nanofibers) to produce water treatment materials (individual composite nanoparticles, hydrogels, aerogels, sponges, membranes, and nanopapers) were covered. Finally, the major challenges and future perspectives concerning the applications of nanocellulose based materials in water treatment and purification were highlighted.

“…Nevertheless, when discarded after use, they pose a threat to environmental pollution [11,12]. Recent advances in adsorption technology addressing using biodegradable and sustainable natural polymers such as cellulose [13][14][15][16][17][18] chitosan [19][20][21][22], ionic chitosan/silica [23], alginate [24][25][26] and starch [27] , oxidized alginate/gelatin decorated silver nanoparticles [25]. For oil water separation, cellulose nanocrystals and polyvinylidene fluoride (PVDF) nanofibers [28,29] and bacterial cellulose and crosslinked cellulose nanofibers membranes were used [30] .The wide use of polymeric materials leads to the waste removal management difficulties.…”

In this study a unique polystyrene sulfonic acid (PSSA) has been synthesized by chemical recycling of waste expanded polystyrene used for fridge packing. Polystyrene sulfonic acid has been used for the preparation of polystyrene composites with silicon dioxide in three percentages 5%, 10%, and 20%. FT-IR, 1 H-NMR, and 13 C-NMR spectroscopic analysis of the obtained materials confirmed their structure. Scanning electron microscopy (SEM) was used to examine the surface morphology of the prepared materials. The crystallinity of the polymer composite was observed through XRD (X-ray diffraction) techniques, and its thermal stability with thermogravimetry (TG) processes was studied. Furthermore, polystyrene sulfonic acid and its composites with silicon dioxide were used as solid adsorbents for decontaminating organic dye-contaminated water. PSSA/Silicon dioxide composites could regenerate the methylene blue MB for a maximum of four cycles without losing their adsorption efficiency.
