Cellulose nanofibril-based aerogel derived from sago pith waste and its application on methylene blue removal

Synthesis, Characterization and Anionic Dye Sequestration Capacity of Cellulose Nanocrystals Derived From Sugarcane Bagasse: Experimental and Regression Modelling

“…This is expected to continue as the population continues to rise and more industries are created. Most pollutants that found their way into water bodies are non-easily biodegradable, recalcitrant, stable to oxidation and are as dangerous as their intermediates and secondary metabolites (Jiang et al 2017;Gautam et al 2019;Beh et al 2020). Methyl orange (MO) is a complex, highly water soluble, azo-structured anionic dye that has found usefulness in laboratories, photography and textile but its discharge in water has been reported to interrupt ecological balance along with disruption of water quality parameters (Keyhanian et al 2016;Huang et al 2017;Zhang et al 2017;Adejumo et al 2020).…”

“…Nanocellulose has found usefulness in medicine, food and construction applications in addition to the environmental remediation of wastes due to its biocompatibility, tensile strength, abundant hydroxyl groups, large surface area and low toxicity (Dufresne, 2013;Hosseinidoust et al 2015;Jorfi and Johan, 2015;Abitbol et al 2016;Hakkarainen et al 2016;Phanthong et al 2018;Wang et al 2019). It has been deployed for remediating dyes, volatile organic compounds, polycyclic aromatic hydrocarbons, heavy metals and pollutants of their likes (Chan et al 2015;Jiang et al 2017;Adejumo et al 2020;Beh et al 2020).…”

“…Nanocellulose is obtainable from cellulosic materials by modifying the crystallinity degree without disruption in functional group reactivities rather enhanced structural activities accompanied with improved morphological assemblage (Jiang et al 2017;Beh et al 2020). It is called cellulose nanofibers (CNFs) when it is extracted by mechanical processes and cellulose nanocrystals (CNC) when it is done using acid hydrolysis.…”

“…Cellulose nanocrystals extracted by acid hydrolysis treatment have been extensively explored and are considered easier compared with other methods of nanocellulose syntheses (Jonoobi et al 2015;Nechyporchuk et al 2016;Oliveira et al 2016;Theivasanthi et al 2018). Nanocellulose has been prepared from widely available, abundant, cost-effective and renewable cellulosic materials such as corncob, corn straw, pineapple leaf, cassava bagasse, cotton, soy hulls, sago pith, kenaf core, rice straw, cocoa bean shell, bamboo, wood, banana leaf, newspaper, jute leaf, groundnut shell, wheat straw, sugarcane bagasse and flax fibre (Abraham et al 2011;Neto et al 2013;Pehlivan et al 2013;Chan et al 2015;Chen et al 2011Chen et al , 2015Bano and Negi, 2017;El Achaby et al 2018;Theivasanthi et al 2018;Buthiyappan et al 2019;Adejumo et al 2020;Beh et al 2020) Sugarcane bagasse is a lignocellulosic fibrous residual waste from sugarcane (Saccharum officinarum) after sequencing its juice. It is widely available and litters carelessly in water and soil in Nigeria.…”

“…Extraction of nanocellulose from sugarcane bagasse is a better alternative owing to nondisruption of inherent chirality, available functional groups, biodegradability and biocompatibility with large surface area, enhanced surface functionality and adsorptive properties (Theivasanthi et al 2018;Adejumo et al 2020;Beh et al 2020).…”
