“…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] .

“…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.

Super absorbent polymers (SAPs) used in sanitary napkin are not required for water absorption capacity as high as in baby diapers and adult incontinence pads. Sanitary napkins must absorb menses, which is delivered at a significantly lower rate and overall daily amount than urines. Thus, the acrylic acid (AA) component can not be strictly necessary. By proper formulation design and processing, polysaccharide SAPs can be equally or even better performing than AA‐containing SAPs in sanitary napkins. Fully biodegradable sodium alginate (SA)‐based SAPs are prepared through ionic cross‐linking by CaCl2 and introduced in female pads. The optimal solution concentrations (SA 8% w/v, CaCl2 0.25% w/v in water) and reaction time are identified, and addition of cellulose nanocrystals (CNC) at different weight contents (0–3 w%) is tested. Morphology, physico‐chemical properties, rheology, free swelling capacity (FSC), centrifuge retention capacity, and weight loss in soil are assessed. Increasing CNC content decreases FSC. Rheology results demonstrate higher storage and loss moduli for SA‐based SAPs versus commercial SAPs. The superior SA‐SAP developed is used in varying amounts for manufacturing sanitary napkin prototypes, revealing that excellent menstrual fluid absorption, surpassing commercial pads. Replacing AA‐based with polysaccharide‐based SAPs would reduce the environmental impact of hygienic product waste.
