A new green hydrogel consisting of cherry stone (CS) powder and sodium alginate (SA) was synthesized through physical crosslinking. The product had a mean diameter 3.95 mm, moisture content 92.28%, bulk density 0.58 g/cm3, swelling ratio 45.10%. analyses its morphological structure functional groups by scanning electron microscopy (SEM) Fourier-transform infrared spectroscopy (FTIR) showed the successful entrapping CS in SA polymeric matrix. viability prepared as adsorbent tested towards Orange II (OII) anionic dye. influence pH, amount, contact time, initial dye concentration evaluated. Then, impact three accelerating factors (stirring speed, ultrasound exposure duration, temperature) on OII retention investigated. highest recorded removal efficiency adsorption capacity were 82.20% 6.84 mg/g, respectively. followed Elovich pseudo-second-order kinetics, adequately described Freundlich Khan isotherms, can be defined spontaneous, endothermic, random. experiments confirmed that obtained used acceptably for at least two consecutive cycles, sustaining effectiveness water decontamination.

Superoleophobic Hierarchical Honeycomb Hydrogels for Effective Heavy Metal Removal in Crude Oil Emulsion

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Фев. 25, 2025

Here, we designed a bioinspired hydrogel surface with underwater superoleophobicity for heavy metal adsorption, effectively addressing the challenge of adsorption site clogging caused by crude oil emulsions. Mimicking reentrant structures lotus leaf undersides, silica dioxide (SiO2) nanoparticles were self-assembled on surface, forming stable hydration layer that imparts unique superoleophobic properties in an aqueous environment. The poly(vinyl alcohol)-sodium alginate-SiO2 capsule (PSSC) exhibited hierarchical honeycomb pore structure nano screen mesh, achieving excellent capacities typical cationic metals (Pb2+, Cu2+, Cd2+, and Cr3+) both solutions optimal pH was determined to be between 4 5, while increasing temperature significantly inhibited process. Maximum Pb2+, Cr3+ reached 291.5 mg/g, 278.7 259.4 171.4 mg/g Competitive observed multicomponent systems, being adsorbed preferentially. mechanisms primarily governed chemical physical electrostatic attraction, functional groups such as −COOH −OH playing key role ion binding. This study demonstrates potential PSSC efficient, cost-effective adsorbent removing from complex matrices, wastewater emulsions, highlights its applicability various environmental remediation scenarios.
