Environmental Applications of Biobased Polydopamine-β-Cyclodextrin-Epichlorohydrin Supramolecular Hydrogel with Tuneable Swelling and Selective Adsorption Behaviors

ACS Applied Polymer Materials, Год журнала: 2024, Номер 6(6), С. 3493 - 3506

Опубликована: Март 8, 2024

Supramolecular hydrogels have been extensively studied for environmental applications owing to their biocompatible, nontoxic, and cost-effective properties. Herein, a polydopamine-β-cyclodextrin-epichlorohydrin (PDA-β-CD-EP) supramolecular hydrogel was facilely prepared through one-pot polymerization using molar ratio of dopamine (DA)/β-cyclodextrin (β-CD)/epichlorohydrin (EP) 1/2/50. Compared with other hydrogels, the can selectively adsorb malachite green from mixed dyes. The structure, surface morphology, thermostability PDA-β-CD-EP were illustrated by FT-IR, SEM–EDX, TGA-DTG, respectively. Interestingly, PDA-β-CD-EP-2 exhibited excellent pH-responsive swelling behavior. influences pH, adsorption time, dosage, initial concentration systematically studied. Under optimal conditions, maximum capacity 652.1 mg/g MG according Langmuir fitting results, much higher than those adsorbents. More importantly, possessed good reproducibility, reusability, biodegradability. Besides, selective mechanism proposed proved, such as hole size shape effect, electrostatic force, host–guest interaction. Overall, this study could provide method prepare biosorbent wastewater remediation.
