Summary: The discharge of wastewater rich in heavy metals and organic substances leads to ecosystem deterioration, environmental pollution, and food pollution. Metal organic frameworks (MOFs) are highly promising materials for wastewater treatment due to their large specific surface area and pore volume, as well as their structure designability. In this study, a novel adsorbent (PEI@UiO-66-NH2) was synthesized and it exhibited improved chemical stability and increased adsorption sites compared to common UiO-66-NH2. The adsorption behaviors of PEI@UiO-66-NH2 were systematically studied, and it was found that it can reach adsorption equilibrium within 5 minutes for Pb(II) and methyl orange (MO). The theoretical adsorption capacities for Pb(II) and MO were found to be 692.80 mg/g and 497.51 mg/g, respectively. The study also established dynamic theoretical adsorption models, providing guidance for scale-up experiments in wastewater treatment. PEI@UiO-66-NH2 showed excellent performance in recycling Pb(II) and MO, indicating its promising application in removing wastewater contaminants.

Summary: The current paper describes the application of newly formulated beads from copper-benzenetricarboxylate (Cu-BTC), polyacrylonitrile (PAN), and chitosan (C), Cu-BTC@C-PAN, C-PAN, and PAN, for the removal of phenolic chemicals from water. The adsorption optimization of 4-chlorophenol (4-CP) and 4-nitrophenol (4-NP) using beads was studied, including the effects of various experimental factors. The Langmuir model and pseudo-second-order kinetic equation were found to be suitable for explaining the adsorption isotherms and kinetics of the system. Cu-BTC@C-PAN beads showed higher adsorption capacities compared to PAN for both 4-CP and 4-NP.

The results showed that spraying MWCNTs and TiO2 NPs on plants reduced the concentration of malondialdehyde (MDA) and hydrogen peroxide (H2O2), increased the oil content, peroxidase (POD) activity, and proportion of unsaturated fatty acids, and enhanced seed yield and weight in Sesamum indicum L. The use of TiO2@MWCNTs was more effective than using separated MWCNTs and TiO2 NPs, and the Shandweel-3 cultivar exhibited greater improvements in growth indicators than the Giza-32 cultivar.

Summary: Green synthesis of zinc(II) metal-organic framework (Zn-MOF) was achieved using spent domestic batteries as a source of Zn metal and benzene dicarboxylic acid as a linker. The synthesized Zn-MOF exhibited similar properties to those reported in literature and remained stable in water. The adsorption of three dyes onto the Zn-MOF followed a pseudo-second-order kinetic model and Freundlich isotherm model. Thermodynamic analysis revealed that the adsorption of one dye was endothermic and spontaneous, while the uptake of the other two dyes was non-spontaneous and exothermic. This study contributes to the development of value-added MOFs from solid waste.
