Exploring the Potential of Biochar Derived from Chinese Herbal Medicine Residue for Efficient Removal of Norfloxacin

Molecules, Journal Year: 2024, Volume and Issue: 29(9), P. 2063 - 2063

Published: April 29, 2024

One-step carbonization was explored to prepare biochar using the residue of a traditional Chinese herbal medicine, Atropa belladonna L. (ABL), as raw material. The resulting biochar, known ABLB4, evaluated for its potential sustainable material norfloxacin (NOR) adsorption in water. Subsequently, comprehensive analysis isotherms, kinetics, and thermodynamics conducted through batch experiments. maximum calculated NOR capacity 252.0 mg/g at 298 K, spontaneous exothermic on ABLB4 could be better suited pseudo-first-order kinetic model Langmuir model. process observed is influenced by pore diffusion, π–π interaction, electrostatic hydrogen bonding between molecules. Moreover, utilization response surface modeling (RSM) facilitated optimization removal efficiency NOR, yielding rate 97.4% temperature 304.8 an initial concentration 67.1 mg/L, pH 7.4. Furthermore, demonstrated favorable economic advantages, with payback 852.5 USD/t. More importantly, even after undergoing five cycles, exhibited consistently high rate, indicating significant application adsorption.

Preparation of artificial humic acid from corn straw and its high-efficiency adsorption on norfloxacin

Journal of Dispersion Science and Technology, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 17

Published: Oct. 13, 2024

In this study, the biomass artificial humic acid (AHA) with efficient adsorption performance for norfloxacin (NOR) was prepared by ultrasonic-assisted acid-alkaline combined hydrothermal method corn straw as raw material. Characterization analysis showed that AHA a typical amorphous structure, and oxygen content of obviously improved compared without method. The saturated capacity 551.53 mg/g, which higher than other reported materials, such high-efficiency is due to abundant oxygen-containing groups (–OH, –C=O, etc.) in AHA, were functional can be π-π stacked, hydrogen bonded electrostatically NOR. It had good selective NOR, less interference from acidity environmental water, coexisting inorganic ions common antibiotics. When it applied adsorb NOR concentration 10.0 mg/L simulated water highest removal rate 91%, indicated could not only remove all polluted complex components at 630 μg/L, but also its far exceeded pollution amount. research important practical significance realizing recycling agricultural wastes pollution.

Sulfonate-Bonded Conjugated Microporous Polymer Hollowed-Out Spheres to Capture Fluoroquinolone Antibiotics and Cationic Dyes from Wastewater

Langmuir, Journal Year: 2024, Volume and Issue: 40(44), P. 23382 - 23397

Published: Oct. 22, 2024

Developing adsorbent materials for the efficient removal of multiple organic pollutants in water is importance technological significance. In present work, a kind conjugated microporous polymer (CMP) with hollow sphere structure was constructed by applying SiO2 nanoparticles as template and 1,3,5-triethynylbenzene (TEB) 2,7-dibromocarbazole (27-DBCZ) building blocks via Sonogashira–Hagihara cross-coupling reaction. order to further improve dispersibility as-resulting CMPs water, hydrophilic (H–S–CMPs) were obtained sulfonation modification. The adsorption performance H–S–CMPs on dyes antibiotics investigated, which based different experimental parameters such initial concentration, contact time, temperature, pH, dose. isotherm, kinetics, thermodynamics also studied, possible mechanism discussed. results illustrated that process more consistent Langmuir isotherm model pseudo-second-order kinetic model. maximum capacities rhodamine B (RhB), methylene blue (MB), ciprofloxacin, norfloxacin 206.2, 324.7, 222.2, 216.9 mg/g, respectively, determined according isothern addition, may be attributed synergistic effects hydrogen bonding, electrostatic attraction, π–π stacking, pore filling. After 5 cycles, still maintained good stability, their rate could reach than 70%. Notably, this polymeric microsphere has been less extensively investigated an antibiotics. As result, designable flexibility unique microspheres, material holds great promise wastewater treatment presence pollutants.
