“…The pseudo-second order kinetic model implied chemisorption during the removal of Hg 2+ ions from simulated wastewater. The diethylenetriaminepentaacetic acid-modified cellulose was obtained by a pre-grafting technique ( Li et al, 2021 ). The adsorbent showed an ultrahigh adsorption capacity of 443.8 mg g −1 for Hg 2+ in aqueous solution.…”

In recent years, faced with the improvement of environmental quality problems, cellulose and cellulose-based (nano) composites have attracted great attention as adsorbents. In this review article, we first report the recent progress of modification and functionalization of cellulose adsorbents. In addition, the adsorbents produced by the modification and functionalization of carboxymehyl cellulose are also introduced. Moreover, the cellulose-based (nano) composites as adsorbents are reviewed in detail. Finally, the development prospect of cellulose and cellulose-based (nano) composites is studied in the field of the environment. In this review article, a critical comment is given based on our knowledge. It is believed that these biomass adsorbents will play an increasingly important role in the field of the environment.

Cellulose is a linear syndiotactic homopolymer, made up of glucose units designated as D‐anhydroglucopyranose units (AGU). The glucose units are connected with each other by b‐(l‐4)‐glycosidic linkage to form a dimeric structure known as cellobiose. These units are assembled into microfibils in a heirarchial manner with excellent strength and stiffness. The properties of cellulose can be further enhanced by either surface functionalization or by converting it to nano form. Nanocellulosic materials are non‐toxic, biodegradable, biocompatible and exhibit enhanced surface properties so widely used for purification of water through adsorption process. This review outlined the most recent updates of uses of cellulose and cellulose derived nano material, composite and nanocomposite as a new class of adsorbents for water remediation.

“…[23][24][25][26] Whereas, these fabrication processes often need multiple steps which were complicated and required strict experimental conditions. [27][28][29] Thus, the design and development of a biosorbent with large surface area for modification and high density of adsorptive groups via simple and easy-controlled preparation process will be beneficial to improve the rapid construction of high-efficiency adsorption system for heavy metal ions.…”

Heavy metal contamination is a serious concern worldwide. In order to remove heavy metal ions from wastewater efficiently, multifunctinoal biomass-based material have been utilized. Herein, hyperbranched polymer modified cellulose biomass (HBP-CB) derived from textile waste materials ramie fibers was successfully developed by construction of Fe3O4/SiO2/polymer multiple structure through an etch-fill strategy. Specifically, Fe3O4 and SiO2 particles were introduced to the oxidation etching cellulose surface, and subsequently modified by hyperbranched polymer The adsorption behavior of the adsorbent toward two classes of heavy metal ions was investigated. The results indicated that HBP-CB owned excellent adsorption capacities for chromium and Cu(II) with maximum 123.5 mg/g and 149.0 mg/g and magnetic recovery performance in aqueous medium. These are owing to the oxidization etching biomass matrix with a higher BET surface area of 4.61 m2/g and the hybrid multiple structure modified by functional hyperbranched polymer with high dense adsorptive sites on the matrix. The adsorption behavior was well described by pseudo-second-order kinetic model and Langmuir isotherm model, revealing a rapid surface adsorption and monolayer spontaneous chemical adsorption. For recycling, 81% of adsorption capacity could be retained after five recovery cycles. These demonstrate that the hybrid multiple structure based on biomass, nanomaterials and polymer could provide sustainable and high-performance adsorption property for wastewater treatment.
