Present work outlines the development of a semi-interpenetrating polymer network (semi-IPN) for the effective removal of hexavalent chromium (Cr (VI)) ions from aqueous solutions. The semi-IPN was synthesized using a 1:1 (w/w) hybrid backbone of nanocellulose and pectin, with itaconic acid grafted onto it through a crosslinker-initiator system comprising N, N’-methylene bisacrylamide (MBA) and ammonium persulfate (APS) under microwave irradiation. Synthesis parameters were optimized using response surface methodology (RSM), resulting in a maximum grafting yield of 172.9%. The semi-IPN achieved an impressive Cr (VI) removal efficiency of 92.2% under optimal conditions: 0.2 g of adsorbent per 25 mL solution, pH 6.0, 120 min contact time, and an initial Cr (VI) concentration of 5 mg/L. Kinetic and isotherm studies indicated that the adsorption process conformed to a pseudo-second-order model and was best described by the Freundlich isotherm. The semi-IPN also showed strong recyclability, retaining 81.4% of its adsorption capacity after five cycles of reuse. These results highlight the potential of the semi-IPN as an effective, ecofriendly and reusable adsorbent for Cr (VI) ion removal.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 4","pages":"2505 - 2524"},"PeriodicalIF":4.9,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bamboo stands out as a promising raw material for papermaking due to its inherent advantages (such as short growth period and high yield). Nevertheless, bamboo pulp exhibits a higher non-fibrous cell content compared to traditional raw materials, and the impact of non-fibrous cells on beating characteristics remains unclear. This study is dedicated to examining the ultrastructure of bamboo fibers and the physical properties of paper, aiming to elucidate the influence of non-fibrous cells on bamboo pulp properties. The results indicated that non-fibrous cells facilitate the formation of fiber ballooning structures, which caused damage and shedding of the outer wall layer, consequently affecting fiber properties. Moreover, non-fibrous cells accelerated the generation of fine fibers during beating, and the formation of fines homogeneous structures. While non-fibrous cells aid in the external fibrillation of bamboo fiber, an excessive amount could impede fiber intertwining and hinder the formation of fiber–fiber joints.

However, the conventional drying of nanocellulose aqueous suspensions tends to result in significant aggregation, which substantially impedes the functionalization of nanocellulose by organic modifying reagents. This study presents an innovative method for drying nanocellulose from aqueous suspension into ultrafine powders while preserving its nanoscale properties. Ammonium bicarbonate was introduced into the aqueous suspension of cellulose nanofibrils (CNFs) to precipitate CNFs that were then dispersed in n-butanol. During the evaporation process, the ammonium bicarbonate decomposed, and the water evaporated, leading to the drying of CNFs in pure n-butanol into an ultrafine powder with high dispersibility. When prepared with a large amount of n-butanol, these ultrafine powders demonstrate enhanced redispersibility in water, with the ability to form a stable suspension through simple agitation. Our research in this paper centers on elucidating the dispersion mechanism of CNF ultrafine powders. We suggest that CNF ultrafine powders dried from n-butanol form a loosely porous mesoporous structure. In the absence of significant changes in crystallinity, the substantial reduction in the inaccessible area of the amorphous regions is likely responsible for their enhanced redispersibility in water. Additionally, by capitalizing on the micro- and nano-structural characteristics of CNF ultrafine powders, we have successfully developed a superhydrophobic coating by applying hydrophobic modification and adhering the treated powder to the surface of filter paper. This outcome not only substantiates the practical applicability of CNF ultrafine powders but also affirms their micro- and nano-dimensional structural attributes. This paper proposes a straightforward and viable approach for the reaction of functionalized organic reagents with nanocellulose, thereby significantly broadening its potential applications.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 4","pages":"2245 - 2260"},"PeriodicalIF":4.9,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
