Cucurbituril-Functionalized Nanocomposite as a Promising Industrial Adsorbent for Rapid Cationic Dye Removal.

摘要: A supramolecular cucurbit[6]uril (CB[6])-enriched magnetic montmorillonite (CBCM) nanocomposite was prepared and characterized. CB[6] played a prominent role as capping agent, helping in better distribution of the nanoparticles, binder between nanoparticles. Montmorillonite provided structural stability fortified ultrafast adsorption toward dyes. Its application removal cationic dyes from wastewater systematically assessed. Process parameters such pH, initial dye concentration, dosage, temperature, time were optimized. Kinetics isotherms process described using pseudo-second-order kinetics Langmuir isotherm, respectively. CBCM exhibited rapid capacity short reaction times with qmax 199.20, 78.31, 55.62 mg g-1 K2 0.0281, 0.0.0823, 0.0953 L mg-1 min-1 for crystal violet, methylene blue, rhodamine B, Benefiting synergetic effects surface hydrophobicity, abundant carbonyl groups CB[6], properties copper ferrite, demonstrated outstanding capacity, negligible leaching at saturation, high tolerance harsh conditions. This intrinsic nature is expedient prolonged industrial operations. To demonstrate viability, syringe filtration continuous flow fixed-bed column operations validated. The stable efficiency 10-100 mL-1 10-50 mL rates. Utilizing catalytic activities ferrite recycled magnet, regenerated, reused several cycles. remarkably improved performance made it suitable different effluent treatment techniques. may pave sustainable way efficient onsite scale.
