Zero‐Waste Production of Copper Nanoparticles and Activated Carbon from Erigeron canadensis L.: A Sustainable Approach for Environmental and Health Applications

ChemistrySelect, Год журнала: 2025, Номер 10(7)

Опубликована: Фев. 1, 2025

Abstract This study presents a novel, zero‐waste process for producing copper nanoparticles (CuNPs), activated carbons (ACs), and oil extract (OE) from plant Erigeron canadensis L. in Sp. Pl.: 863 (1753). method optimizes resource utilization eliminates waste, offering sustainable approach to green synthesis. The NPs were characterized using XRD, SEM, FTIR. Their effectiveness was evaluated through comparative studies on methylene blue removal, antioxidant capacity, antibacterial activity. prepared OE exhibited superior properties, particularly against Klebsiella pneumoniae subsp . ATCC 13883 (inhibition zone: 19 ± 0 mm) Proteus vulgaris RSKK 96029 18.7 0.6 mm). AC demonstrated exceptional dye adsorption efficiency, ranging 98.62% 99.50%. Antioxidant tests revealed that CuNPs possessed strong with an IC 50 of 0.023 0.002 mg/mL the DPPH radical scavenging test 0.41 0.07 iron chelation test. lower capacity (0.43 0.01) but significant iron‐chelating ability (41.94 1.06). In comparison, standard antioxidants EDTA BHT showed their respective tests. These experimental findings underscore potential this bio zero‐waste‐derived products environmental biomedical applications, highlighting its broad applicability.

Adsorption of Cu(II) and Pb(II) in Aqueous Solution by Biochar Composites

ACS Omega, Год журнала: 2025, Номер 10(14), С. 13816 - 13828

Опубликована: Апрель 2, 2025

In this study, straw biochar (TB) was prepared by pyrolysis at 500 °C, and composite material (TBS) a 1:4 mass ratio with sludge (TS). Scanning electron microscopy Fourier transform infrared spectroscopy were utilized to characterize the before after adsorption. The results demonstrated that TBS possesses significant pore structure characteristics abundant active functional groups such as hydroxyl, carboxyl, carbonyl groups, providing structural basis for its efficient adsorption of heavy metal ions in aqueous solutions. performance remediation materials Cu(II) Pb(II) solution systematically investigated. Experimental data showed achieved maximum capacities 60.86 46.98 mg/g equilibrium, respectively, exhibiting superior efficiency. Through fitting analysis using kinetic models isothermal models, it found pseudo-second-order model Freundlich could more accurately describe process two ions, indicating chemical dominant mechanism characterized multilayer Thermodynamic parameter calculations revealed negative ΔG values positive ΔH ΔS values, suggesting spontaneous, entropy-increasing, endothermic reaction. These research fully validate excellent removal capabilities Pb(II). This study has shown can be considered promising cost-effective adsorbent, demonstrating potential adsorb water.
