Tetracycline’s accumulation in the environment poses threats to human health and ecological balance, necessitating efficient rapid removal methods. Novel porous metal–organic framework (MOF) materials have garnered significant attention academia due their distinctive characteristics. This paper focuses on studying adsorption performance of amino-modified MIL-101(Fe) towards tetracycline, along with mechanisms. The main research objectives conclusions are as follows: (1) NH2-MIL-101(Fe) MOF were successfully synthesized via solvothermal method, confirmed through various characterization techniques including XRD, FT-IR, SEM, EDS, XPS, BET, TGA. (2) exhibited a 40% enhancement tetracycline compared MIL-101(Fe), primarily chemical following pseudo-second-order kinetics. process conformed well Freundlich isotherm models, indicating multilayer heterogeneous Thermodynamic analysis revealed spontaneous endothermic reaction. (3) An increased adsorbent dosage temperature correspondingly improved NH2-MIL-101(Fe)’s efficiency, optimal observed under neutral pH conditions. These findings provide new strategies for effective from environment, thus holding implications environmental protection.

The removal of tar and CO2 represents a critical challenge in the production biomass gasification syngas, necessitating development advanced catalytic systems. In this study, plasma-enhanced reforming was employed to remove tar, with toluene selected as model compound for tar. Supported Nix-Fey/Al2O3 catalysts, varying Ni/Fe molar ratios (3:1, 2:1, 1:1, 1:2, 1:3), were synthesized dielectric barrier discharge (DBD) non-thermal plasma reactors. experiments conducted at 250 °C ambient pressure. effects various ratios, powers, concentrations on DBD plasma-catalytic synthesis gas analyzed. results indicate that CO H2 are primary gaseous products decomposition, selectivity these increasing power. Increasing power leads higher production. A CO2/C7H8 ratio 1.5 found effectively enhance performance system, leading highest conversion syngas selectivity. catalysts follows following order: Ni3-Fe1/Al2O3 > Ni2-Fe1/Al2O3 Ni1-Fe1/Al2O3 Ni1-Fe2/Al2O3 Ni1-Fe3/Al2O3. Notably, catalyst exhibits high adsorption capacity due its strong basicity, demonstrating significant potential both carbon resistance.
