“…Researchers have also explored its efficiency in the removal of heavy metals. [32][33][34] Pollutants present in effluent such as organic dyes contain a positive charge which helps in forming a bond with the hydroxyl group of cellulose-based adsorbent (CBA). [32,35] Moreover, broad research has been done in the past on the remediation of azo dyes.…”

“…As already discussed in the preceding paragraphs, cellulose as a natural or modified has been used for synthesis and application in the removal of dyes. Researchers have also explored its efficiency in the removal of heavy metals [32–34] . Pollutants present in effluent such as organic dyes contain a positive charge which helps in forming a bond with the hydroxyl group of cellulose‐based adsorbent (CBA) [32,35] …”

“…In addition, RB19 dyes are resistant to photo-degradation and chemical agents due to the presence of aromatic structures. [40] Hence, the primary objective of the current research is to synthesize an adsorbent using cellulose as a precursor [33] and to determine a region of vector space in which operating parameters are satisfied for the removal of RB19 dye using synthesized CBA, economically and sustainably. Following that, the Box Behnken method was used to optimize a range of chemical and physical processes.…”

This study attempts a successful synthesis of a cellulose‐based adsorbent using orthophosphoric acid as a chemical activating agent followed by pyrolysis. A detailed characterization of synthesized adsorbent in terms of its morphology, material crystallinity, and surface area was studied. Batch studies were performed to remove reactive blue 19 dye from its simulated wastewater. The impact of various adsorption parameters such as adsorbent dosage (A: 0.1 to 0.5 g), initial dye concentration (B: 100 to 500 mg/L), contact time (C: 10 to 180 min), pH (D: 2 to 10), temperature (E: 35 to 60 °C) were examined and optimized using on Box‐Behnken method with Response Surface Methodology. The experimentally obtained adsorption data were fitted to different isotherms and kinetic models. The findings prove that more than 96 % of 400 mg/L of RB19 dye removal is possible with 4 g/L dosage in 18.5 min at 50 °C with its original pH of 6.8. Also, three cycles of regenerability and reusability of CBA gives 51.88 % of RB19 dye removal. Moreover, the possibility of using spent adsorbent in the boiler as a fuel was explored. Consequently, this research will contribute to SDG6 by maintaining circularity and sustainability in the entire process.
