The textile industry is one of the biggest water consumption production areas and its waste is essential to cause ecological contamination as they deliver questionable color, weighty metal, and degradable natural and inorganic results whenever arranged without treatment. The natural treatment strategy is not broadly drilled because of its intricate method. In the adsorption method, for example, actuated carbon was limited by prudence of its significant expense and low adsorption limit. This study has completed the combination and portrayal of bagasse cellulose-based hydrogel for the expulsion of methylene blue color from textile industry wastewater. The study furnishes a major critical contributing option for biodegradable adsorption material by supplanting the conventional color evacuation method with a nonconventional one that showsthe attainability of horticultural waste for a union of the hydrogel as opposed to noninexhaustible petrochemical based and show the capability of involving hydrogel for the expulsion of harmful contamination from the textile industry. The hydrogel was combined utilizing free extreme polymerization that can utilize acrylic corrosive (AA) and citrus extract as cross-connecting specialists and monomers individually. FTIR, XRD, and conduct metric titration are the primary hardware utilized for the portrayal of the hydrogel. The cycle boundaries that can influence the color evacuation proficiency of hydrogel, for example, pH, contact time, and temperature have been examined. A focal composite plan by rotatable component is the technique used to browse reaction surface strategies to control the tests with the communication of cycle boundaries.

Since textile finishing goes through bleaching, dyeing, finishing, and publishing, various chemicals, colorings, and a huge amount of water were used in each finishing stage which is the reason for the generation of a high amount of toxic and dangerous effluent including color, heavy substance, and degradable organic and inorganic salts [4]. Recently, the textile industry has the potential to release 51% of sewage waste annually. From this, greater than 70 billion ton per year is discharged from the dyeing process [1]. Those wastes were characterized by high values of BOD, COD, TSS, TDS, TS, high shifting pH, and strong colors which are the primary cause of mortal health and submarine life. Wastewater effluents with a high level of COD can be toxic to biological life [5]. The presence of BOD in textile wastewater leads to the rapid depletion of dissolved oxygen [5]. To a great extent, treatment options widely practiced in decolorization were the physical method, chemical method, and biological method [4] that can be applied. Among the raised mechanisms of dye elimination through adsorption, the method is simply eloquent and sensible because of it being cheap, getting rid of an extensive variety of compounds from the commercial wastewater, having an excessive floor region that allows adsorption, and time being powerful than different remedy methods [6]. A lot of researchers have done gel preparation but have not focused on the gel from bagasse cellulose [7].

Most of the time, hydrogel was synthesized via esterification, free radical polymerization, graft polymerization, cross-linking, and ionization radiation [8]. Cross-linking agents play a massive role in the equilibrium swelling degree and elastic modulus of the hydrogel; the nature of the agent can differ from residences of the adsorbent [9]. Hydrogel from cellulose is a superabsorbent that can absorb and retain huge amounts of water or aqueous solutions [10]. It has great industrial applications in addition to the textile industry such as (a) hygienic and bio-related uses (more specifically in disposable diapers); (b) agricultural uses (such as water reserving in soil, soil conditioning, and controlled release of agrochemicals); (c) pharmaceutical dosage forms; (d) separation technology; (e) paper industries (such as in wastewater treatment); (f) water-swelling rubbers; (g) soft actuators/valves; (h) electrical applications; (i) construction, packaging, and artificial snow; (j) sludge/coal dewatering; and (k) fire extinguishing gels [10]. This study covered the synthesis and characterization of bagasse cellulose-based hydrogel for the removal of methylene blue dye from textile industry wastewater.

Treatment of cation dye will become not an unusual placethat trouble over an extended duration of time, in addition, one million tons of cation dye such as methylene blue dye which is produced yearly and large cited for dangerous illnesses like carcinogenetic and mutagenic, growing heartbeat, vomiting, surprising, and any other not unusual place relative disease [2]. Hydrogels have been established to be tremendous dye-adsorbent substances with extraordinarily excessive quantities of methylene blue adsorption [2]. Synthesis of bagasse cellulose polymer-based hydrogel for the intention of dye removal has been taken into special consideration due to its abundance, renewability, biodegradability, and biocompatibility. More than 100 million tons of SB are produced worldwide annually.

Raw sugar cane bagasse becomes washed with the usage of distilled water till impurities and a small number of sugar constituents are left after juice extraction. Then, the moist bagasse allowed to dry by exposing it to daylight for one susceptible day and it is been grounded for an additional work.

Raw sugar cane bagasse turns into washed using distilled water until impurities and a small number of sugar parts are left after juice extraction. Then, the wet bagasse was allowed to dry by exposing it to sunlight for one week and it was grounded for additional work.

Proximate analysis for sugarcane bagasse was conducted as per the standard ASTM method conducted by authors [13] at the Department of Bioenergy, Agricultural Engineering College and Research Institute. This proximate analysis includes moisture, ash, volatile matter, and fixed carbon contents reported in the result section.

The proximate analysis result of bagasse determines the distribution of its contents. It may be noted that the volatile matter present in bagasse contributes maximum to its contents. The moisture content present in the sample can also be considered water vapor when it is heated to high temperatures.

During the swelling study, high weight increment of swollen hydrogel was shown after a two-day immersing period, which gains 4182.5% of the swelling degree of the synthesized hydrogel. Regularly. the meshes of the network in the rubbery phase started to expand, allowing other solvent molecules to penetrate the hydrogel network [40]. The properties of swelling of bagasse cellulose hydrogel were calculated using equation (1). This value was in agreement with the literature that highly swollen hydrogel achieves a high adsorption capacity of methylene blue dye pollutants from the textile industry [41].

Based on the proximate analysis result, sugar cane bagasse has maximum volatile matter and minimum ash content. Therefore, the analysis gives evidence for sugar cane bagasse as the precursor used for activated CarbonCript.

The study is focused on the analysis of hydrogel from bagasse cellulose and its application for dye removal from textile wastewater. As observed from crystal size analysis extracted cellulose is more crystal than not extracted cellulose. There is the β-glycosidic bond linkage between cellulose and the hemicellulose structure of the starch. The produced gel has a crystal matrix structure which can be helpful to trap small molecules. The water absorbance capacity of the hydrogel is high due to the more crystal structure of its structure which leads to swelling behavior. Basicity based on cellulose purification results in a high-quality pure product. We want to recommend further studies to change the surface area of the produced gel for further efficiency of removal or trapping behaviors of the produced gel.

Lignin in sugarcane bagasse (SB) hinders its utilization by microorganism, therefore, pretreatment methods are employed to make fermentable components accessible to the microbes. Multivariate analysis of different chemical pretreatment methods can aid to select the most appropriate strategy to valorize a particular biomass.

Sugarcane bagasse (SB) is one of the abundant, low-cost agricultural deposits in the world which is mainly composed of lignin, hemicellulose, cellulose, wax and ash [1]. Owing to its site availability at sugar industries, SB can be used to generate additional revenues by utilizing it for the synthesis of chemicals, fuels and enzymes [2]. Pakistan, China, Mexico, India, Philippines, Thailand and Brazil are the major sugarcane producing countries [3] and therefore, can be befitted by adopting SB-based technologies. SB is a polysaccharides rich waste and hence a promising raw material in context of biorefineries [4] which can be utilized in various transformation processes. Therefore, the advances in biorefineries from SB have been investigated in numerous studies, with an immense range of configurations [5]. Sugar monomers like xylose and glucose can be obtained from SB which can be utilized in fermentation process to produce xylitol, lactic acid, ethanol, succinic acid, biopolymers, arabitol, electricity and antioxidants [3, 6].

Energy security and environmental conservation issues are likely to remain two of the major long-term challenges facing human existence globally (Sheikhdavoodi et al. 2015). Meanwhile, lignocellulose biomass such as sugarcane bagasse (SCB), corn stover, cereal straw, and forest woody residue (e.g., birch, spruce, eucalyptus) are substances with a high energy content that can assuage the impending energy crisis (Yin 2011; Ajala et al. 2020). They are organic materials obtained from biological sources, mostly plants biomass which is the most abundant global source of renewable materials and their annual global production has been estimated to be 1010 MT (Ajala et al. 2020). The SCB is one of these residues that are in abundance globally, which has the key to solving the global energy problem and environmental concern (Scaramucci et al. 2006). 041b061a72
