Synthesis of chitosan composite of metal-organic framework for the adsorption of dyes; kinetic and thermodynamic approach

Tooba Saeed et al.

Summary: The iron metal-organic framework composite CS/MOF-235 was synthesized and its adsorption performance for methylene blue and methyl orange was investigated. The results showed that CS/MOF-235 had much higher adsorption capacity than MOF-235 and chitosan. The adsorption mechanisms may involve hydrogen bonding, pi-pi bonding, pore-filling, electrostatic interactions, and chemisorption.

Enhanced adsorptive removal of carbendazim from water by FeCl3-modified corn straw biochar as compared with pristine, HCl and NaOH modification

Yanru Wang et al.

Summary: Carbendazim residues present in water worldwide pose a potential risk to water ecosystems and human health. In this study, corn straw biochars were prepared and modified with acid, alkali, and iron magnetization to remove carbendazim from water. The results showed that iron-modified corn straw biochar (BC700M) had the highest adsorption capacity for carbendazim. BC700M demonstrated promising potential as a sustainable adsorbent for carbendazim removal.

3D, eco-friendly metal-organic frameworks@carbon nanotube aerogels composite materials for removal of pesticides in water

Wenlong Liang et al.

Summary: A novel method of loading two MOFs onto carbon nanotube aerogels was developed, showing synergistic effects between MOFs and MPCA in enhancing adsorption capacity for herbicides. The prepared MOF@MPCA demonstrated strong adsorption capability, with UiO66-NH2@MPCA showing an equilibrium adsorption capacity of 227.3 mg/g and reusability for 5 cycles. Additionally, biosafety experiments indicated that MPCA can reduce the risks of MOFs nanoparticles leakage and accumulation in organisms.

Adsorption mechanism of two pesticides on polyethylene and polypropylene microplastics: DFT calculations and particle size effects*

Qiming Mo et al.

Summary: Polyethylene (PE) and polypropylene (PP) microplastics (MPs) act as carriers for pesticides like carbofuran and carbendazim (CBD), showing high adsorption rates and capacities. The presence of dissolved organic matter (DOM) affects the adsorption behavior, with larger MPs having lower capacities. The primary adsorption mechanisms are through intermolecular van der Waals forces, with electrostatic interactions explaining the higher adsorption of CBD compared to carbofuran by MPs.
