Mechanism of Enhanced Fluoride Adsorption Using Amino-Functionalized Aluminum-Based Metal–Organic Frameworks

Water, Journal Year: 2024, Volume and Issue: 16(20), P. 2889 - 2889

Published: Oct. 11, 2024

Due to the increasing fluoride concentrations in water bodies, significant environmental concerns have arisen. This study focuses on aluminum-based materials with a high affinity for fluorine, specifically enhancing metal–organic frameworks (MOFs) amino groups improve their adsorption and defluorination performance. We systematically investigate factors influencing mechanisms governing behavior of amino-functionalized MOF aqueous environments. An SEM, XRD, FT-IR characterization confirms successful preparation NH2-MIL-101 (Al). In 10 mg/L ion solution at pH 7.0, removal efficiency increases dosage (Al), although marginal improvement decreases beyond 0.015 g/L. Under identical conditions, capacity (Al) is seven times greater than that (Fe). demonstrates effective across broad range, superior uptake acidic conditions. At concentration 7 mg/L, g 3.0, equilibrium achieved within 60 min, 31.2 mg/g. analysis using isotherm models reveals follows monolayer model, while kinetic studies indicate predominant mechanism chemical adsorption. research provides scientific basis advanced treatment fluoride-containing wastewater, offering theoretical practical contributions.

Assessing the Environmental Impact of Municipal Waste on Energy Incineration Technology for Power Generation Using Life Cycle Assessment Methodology

Toxics, Journal Year: 2024, Volume and Issue: 12(11), P. 786 - 786

Published: Oct. 29, 2024

The life cycle assessment methodology is a comprehensive environmental impact evaluation approach rooted in the "cradle-to-grave" concept. This study takes municipal solid waste incineration power plant central China as an example to comprehensively explore potential ecological and impacts of generation through methods. Burning one ton can recover 7342 joules thermal energy. Compared with traditional landfill, reduce greenhouse gas emissions by about 30%, global warming -0.69 kg carbon dioxide equivalent. Amongst impacts, land, freshwater, marine ecosystems possess greatest toxicity, followed harmful effects on human health influence ozone-producing photochemical pollution. Lastly, there comes terrestrial acidification, whereas other types be relatively disregarded comparison. In process generation, warming, ionizing radiation, fossil resource scarcity are less than zero, indicating that this environmentally friendly process. response above-mentioned it necessary pay attention improving efficiency, optimizing leachate treatment, reducing coal use, controlling acidic urban generation. research offers insights into advancing sustainable technologies for utilizing energy resource.

Published: Feb. 21, 2025

Nitrogen-doped graphene-coated Fe nanoparticles ([email protected]) were synthesized through the pyrolysis of a durian peel-supported urea ferric salt mixture. These materials subsequently utilized to activate peroxymonosulfate (PMS) for oxidation terramycin (TEC). The incorporation an optimal amount and nitrate during synthesis significantly improves catalytic activity resulting catalysts after pyrolysis. Using [email protected] catalyst at concentration 0.10 g L−1, 98.55% 20 mg L−1 TEC is achieved within 60 min. Additionally, exhibits exceptionally low metal leaching, with levels remaining below 0.25 L−1. shows remarkable stability effectively resists interference, reusability, robust throughout process. mechanism [email protected]/PMS/TEC system determined, 1O2 main reactive oxygen species (ROSs). XPS analysis confirms that primary active sites are Fe0, as well nitrogen-doped regions carbon matrix. This research demonstrates by integrating iron nitrogen peel, it possible develop PMS activator satisfactory performance degradation environmental pollutants.
