Facile synthesis of amine functionalized silica coated iron oxide nanoparticles for highly efficient removal of cefixime and ceftriaxone from wastewater

Separation Science and Technology, Год журнала: 2024, Номер 60(2), С. 234 - 249

Опубликована: Дек. 9, 2024

A novel adsorbent, amine-functionalized porous silica-coated iron oxide nanoparticles (Fe3O4@SiO2-NH2) was prepared for the removal of cefixime (CFX) and ceftriaxone (CFT) from water. The adsorbent then characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy, transmission particle size, surface area pore size analysis. amine functionalized silica coated are 110 nm, 1073 m2/g 40 Å, respectively. effect dose, concentration, time duration, temperature pH were evaluated. At optimum conditions, efficiency CFX CFT found to be 94.53% 88.3%, adsorption data onto Fe3O4@SiO2-NH2 fully fitted with Freundlich isotherm followed pseudo-2nd order kinetic model. has strong interaction through hydrogen bonding. regenerated reused 30 times, it that dropped only 10%. Owing high easy preparation method, could used as an efficient nano-adsorbent antibiotics other emerging contaminants wastewater.

Adsorption of Ciprofloxacin and Lidocaine by Non-Fibrous Raw Mg-Clays: The Role of Composition and Texture

Minerals, Год журнала: 2024, Номер 14(10), С. 966 - 966

Опубликована: Сен. 25, 2024

This study evaluated non-fibrous Mg-clays as potential adsorbents of emerging contaminants (ECs) from water. The materials were characterized, and their textural structural properties related to ability remove two model EC molecules: ciprofloxacin (CPX) lidocaine (LID). results showed that Ad-6 Ad-7 are mixed-layer kerolite/stevensite, while Ad-5 Ad-8 mainly composed smectite minerals like stevensite saponite, respectively. exhibited the highest CPX-adsorption capacity (0.91 mmol·g−1 clay), likely due its saponite content. Mixed-layer also performed well, with achieving an adsorption 0.8 0.55 clay, Adsorption studies suggested CPX is adsorbed through ion exchange in high content (Ad-8 Ad-5), interstratified enhanced retention kerolite presence, which improves porous structures. Similar findings observed for LID, indicating a cationic-exchange mechanism LID all suggesting molecular size could regulate removal these materials. work studied be effectively used pharmaceutical pollutants, expanding commercial possibilities.

Synthesis of Iron Oxide/Activated Hydrochar Composite from Residual Brewery Biomass for Remediation of Water Contaminated with Chlorophenol

Research Square (Research Square), Год журнала: 2024, Номер unknown

Опубликована: Ноя. 14, 2024

The study aimed to develop an iron oxide/activated hydrochar composite (FeOHC) remove 2-chlorophenol from water through adsorption or oxidation processes. Two preparation methods were used: (1) incipient wetness impregnation of biomass via hydrothermal carbonization, and (2) coprecipitation oxide on the surface (FeOHC-C). Both materials activated at 400°C under nitrogen. Characterization revealed mesoporous structures with areas 44–66 m² g⁻¹ magnetite presence. Adsorption experiments showed a capacity 7.71 5.14 mg within 24 hours, Elovich model best describing kinetics. Equilibrium ranged 24.63 18.70 g⁻¹, FeOHC showing highest capacity, fitting Sips isotherm model. Thermodynamic analysis suggested physical process. Fenton reactions demonstrated faster removal pH 3.0, while reusability tests confirmed could act as both adsorbents self-regenerative catalysts for remediation.
