Cellulose nanocrystals (CNCs) as a bio-based adsorbent material have been synthesized at mild temperature reaction conditions using acid hydrolysis of microcrystalline cellulose (MCC) by sulfuric acid. CNCs by a simple acid treatment become enriched with negatively charged surface functionalities and shows good adsorption capacity. The CNCs have been characterized by X-ray photoelectron spectroscopy, Fourier transform Infrared, X-ray diffraction spectroscopy, and thermogravimetric analysis for their chemical composition, functionality, crystallinity, and stability, respectively. Sulfated CNCs have been used to selectively remove the toxic Janus Green (JG) dye tested out of many other dyes via adsorption and showed a Langmuir adsorption capacity of ∼77 mg g. −1 The effects of pH, temperature, concentration, and loading capacity have also been explored. The adsorption kinetics follows the pseudo-second-order pathway and thermodynamic analysis of the system indicates that the process is exothermic and spontaneous. Moreover, for the practical applicability of the proposed method, the adsorption of JG was also analyzed in four spiked industrial samples collected from nearby textile industries, where they removed more than 80% of the dye from the complex industrial water system.

“…For example, high cation exchange cetyltrimethylammonium bromide modified montmorillonite (CTM) has been used as an additive for CNC scaffold, where the composite was effective for adsorption of diurona potential carcinogenic herbicide. 452 Pristine CNC displayed a surface area of 27.23 m 2 /g, which was increased to 39.51 m 2 /g in CNC/CTM composite. It was found that around 70 mg/L of the composite was needed to adsorb 6.0 mg/L of diuron, which was below the permissible level of diuron in drinking water (100 mg/L) set by the US Environmental Protection Agency.…”

Nanocellulose for Sustainable Water Purification

Nanocelluloses (NC) are nature-based sustainable biomaterials, which not only possess cellulosic properties but also have the important hallmarks of nanomaterials, such as large surface area, versatile reactive sites or functionalities, and scaffolding stability to host inorganic nanoparticles. This class of nanomaterials offers new opportunities for a broad spectrum of applications for clean water production that were once thought impractical. This Review covers substantial discussions based on evaluative judgments of the recent literature and technical advancements in the fields of coagulation/flocculation, adsorption, photocatalysis, and membrane filtration for water decontamination through proper understanding of fundamental knowledge of NC, such as purity, crystallinity, surface chemistry and charge, suspension rheology, morphology, mechanical properties, and film stability. To supplement these, discussions on low-cost and scalable NC extraction, new characterizations including solution small-angle X-ray scattering evaluation, and structure− property relationships of NC are also reviewed. Identifying knowledge gaps and drawing perspectives could generate guidance to overcome uncertainties associated with the adaptation of NC-enabled water purification technologies. Furthermore, the topics of simultaneous removal of multipollutants disposal and proper handling of post/spent NC are discussed. We believe NC-enabled remediation nanomaterials can be integrated into a broad range of water treatments, greatly improving the cost-effectiveness and sustainability of water purification.

“…Likewise, Mautner et al (2017) demonstrated that the cationic cellulose nanopaper membranes are efficiently useful for the continuous removal of nitrates, released from the chemical fertilizer in the agriculture soil and irrigation water [108]. Similarly, several researches revealed that the nanocellulose can serve as a potential adsorbent for the removal of pesticides, such as chlorpyrifos [143], tetraconazole [144], diuron [145], organophosphorus [146], difenoconazole, and nitenpyram [147]. Nanocelluloses are also employed for the adsorption and elimination of hazardous drugs from industrial wastewater, such as ciprofloxacin, diclofenac [124], metronidazole [148], and ceftriaxone [149].…”

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.
