This study introduced a novel type of biochar–titanate nanosheet (BC@TNS) composite for the selective adsorption Pb(II) from wastewater containing various heavy metal ions. The biochar derived lignin–carbon pyrolysis forms scaffold, while titanate nanosheets coat it via an alkaline hydrothermal reaction. synthesis was confirmed through analytic characterizations, revealing distinctive morphology TNS nanoflowers consisting numerous incorporated into BC support. BC@TNS achieved maximum capacities 37.89 mg/g Pb(II), 13.38 Cd(II), and 8.47 Zn(II), demonstrating its remarkable selectivity Pb(II). Kinetic studies using Weber–Morris, PFO, PSO models indicated that primarily driven by chemisorption, whereas Cd(II) Zn(II) were predominantly governed physisorption. Isotherm analysis Langmuir, Freundlich, Dubinin–Radushkevich, Temkin revealed involved both monolayer multilayer processes, monolayer. Detailed insights scanning electron microscopy (SEM-EDS) X-ray photoelectron spectroscopy (XPS) analyses further elucidated these mechanisms. superior validated in multicomponent simulated HMs 10 co-existing ions, maintaining high efficiency 75.68%, highlighting potential Pb recovery. Moreover, adsorbent demonstrated excellent regeneration capacity recyclability. shows great efficient removal ions wastewater, offering sustainable solution environmental protection.

A mesoporous calcium-bearing siliceous framework (Ca-MCM-41) was synthesized using natural coral reef carbonate rocks as precursors. The structural characterization, confirmed through XRD, SEM, FT-IR, and BET analyses, validated the formation of MCM-41 with well-defined properties a high surface area 159.6 m2/g. developed Ca-MCM-41 evaluated potential adsorbent for removal Sr2+ B3+ ions from both aqueous solutions real seawater samples collected Gulf Suez, Egypt. adsorption capacity at saturation reached 285.9 mg/g 86.1 B3+, demonstrating framework's affinity these contaminants. mechanisms were elucidated steric energetic parameters, derived statistical physics-based isotherm models. exhibited higher active site density (148.9 mg/g) compared to (54.8 mg/g), explaining its superior sequestration performance strontium ions. Each receptor capable accommodating up three 2 ions, indicating multi-ionic interaction process preferential vertical alignment during adsorption. Energetic analysis revealed that occurred via physical energies below 7 kJ/mol, alongside exothermic spontaneous behavior, evidenced by calculated internal energy, entropy, enthalpy values. structure demonstrated notable efficiency in applications, achieving percentages 80% 64% considering their average concentrations (24.2 mg/L 12.85 B3+) 1-L volume. These findings highlight an effective sustainable environmental water treatment applications.
