A novel application of cellulose aerogel composites from pineapple leaf fibers and cotton waste: Removal of dyes and oil in wastewater

In a world where demands for freshwater are ever-growing, wastewater remediation becomes global concern. Especially, water, which is contaminated by oil, dyes, poses challenges to the management of water resources. The development innovative processes treatment still major obstacle. With regard its fast removal rate and environmental compatibility, cellulose aerogel composites recently considered as potential contributor remediation. this study, fabricated using sol–gel method from two-agroindustrial wastes: pineapple leaf fibers cotton waste in alkali-urea solution followed freeze-drying. prepared extremely lightweight with low density (0.053 − 0.069 g cm−3) high porosity nearly 95%. It worth noting that mechanical strength remarkably improved their Young’s modulus increasing 5–9 times compared previous polyvinyl alcohol binder. as-synthesized directly applied adsorb cationic methylene blue exhibit maximum adsorption uptake 34.01 g−1. methyltrimethoxysilane-coated also show ability deal oil pollution capacity 15.8 g−1 within only 20 s. Besides removal, our developed have demonstrated capability treating dye-contaminated first time based on evidenced eliminate blue.
