    Hybrid Heroes of Water Treatment: the Rise of Biochar-Modified Metal Organic Frameworks
    (Elsevier Science Sa, 2026) Gungormus, Elif; Goren, A. Yagmur; Khataee, Alireza
    Biochar-metal organic framework (BC-MOF) composites are highly promising for water treatment due to their synergistic properties. In this regard, this review paper highlights their outstanding performance in removing various pollutants from water. The applications of these composites cover various environmental remediation processes, such as adsorption, photocatalysis, persulfate activation, and Fenton-like degradation. BC-MOF composites have demonstrated high performance in environmental applications, achieving pollutant removal efficiencies exceeding 90 % through adsorption and photocatalytic degradation. Moreover, degradation processes through advanced oxidation pathways, which produce active radicals, such as hydroxyl and superoxide radical-mediated breakdowns, significantly enhance the mineralization of organic pollutants. Many composites also retained >80 % of their initial capacity after 4-6 cycles, indicating good reusability. Overall, BC-MOF composites present a sustainable, high-performance solution for contaminant removal, with broad applicability against antibiotics, dyes, heavy metals, pesticides, and fluoride ions.

    Modification of Grape Pulp With Citric Acid for the Production of Natural Ion Exchanger Resin and Removal of Pb (ii) and Cd (ii) From Aqueous Solutions: Kinetic, Thermodynamics, and Mechanism
    (Springer Science and Business Media Deutschland GmbH, 2023) Arslanoğlu, E.; Eren, M.Ş.A.; Arslanoğlu, H.; Çiftçi, H.
    In this study, grape pulp (MGP) modified with NaOH and citric acid was used in the production of natural ion exchangers. The effects of parameters such as initial pH, MGP dosage, temperature, initial metal ion concentration, and contact time on the removal of Pb (II) and Cd (II) ions from aqueous solutions using modified materials were investigated by batch experiments. It was found that the experimental kinetic data fit the second-order model, and the activation energy for Pb (II) and Cd (II) adsorption processes were 20.68 and 38.61 kj mol−1, respectively. Although the initial adsorption rate increases with increasing temperature, the adsorption efficiency slightly decreases. It was calculated that the equilibrium data fit the Langmuir isotherm better, and the maximum adsorption capacities for Pb (II) and Cd (II) adsorption processes were approximately 1.496 and 1.022 mmol g−1 at 25 °C, respectively. Thermodynamic analysis has shown that the adsorption processes of Pb (II) and Cd (II) are exothermic (ΔH°Pb = −35.68 kj mol−1, ΔH°Cd = −21.19 kj mol−1) and have a self-developing character.
