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 m 2 /g. developed Ca-MCM-41 evaluated potential adsorbent for removal Sr 2+ B 3+ ions from both aqueous solutions real seawater samples collected Gulf Suez, Egypt. adsorption capacity at saturation reached 285.9 mg/g 86.1 , 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 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 ) 1-L volume. These findings highlight an effective sustainable environmental water treatment applications.

At present, soil contaminated with arsenic (As) and antimony (Sb) is escalating at an alarming rate, which harmful to human health. In this study, Fe- Mn-modified activated carbon (AC) biochar (BC) were prepared compared for the remediation of As- Sb-contaminated soil. The effects on speciation As Sb, pH, organic matter (SOM), enzyme activity various dosages times investigated. results showed that whole, best stabilization effect Sb was achieved 3% FeMnBC. Furthermore, increases in time dosage, immobilization more significant. Fe/Mn-modified AC BC enhanced MnAC being particularly effective; FeMnAC demonstrated most pronounced enhancement SOM. modified materials exhibited a dramatic increase enzymatic activity. particular, urease increasing trend, catalase first decreased then increased over 30 days. Among treatments, significant enhancements activities, whereas 1% FeMnBC had sucrase This study provides theoretical support co-contaminated by BC.

Both biochar and layered double hydroxide (LDH) have drawbacks in regard to the removal of heavy metals. The combined application LDH not only solved problem easy agglomeration but also effectively improved metal adsorption capacity biochar. In this work, a MgFe–LDH banana straw composite (MgFe–LDH@BB), with regular hydrotalcite structure, was synthesized by employing simple hydrothermal method. showed an ultra-high for lead (Pb), cadmium (Cd), zinc (Zn) water. A series experiments were conducted investigate characteristics MgFe–LDH@BB. At pH = 6.0, MgFe–LDH@BB demonstrated effective Pb, Cd, Zn. addition, results that Zn rapid conformed pseudo-second-order kinetic Langmuir models, indicating single-layer chemical adsorption. maximum 1112.6, 869.6, 414.9 mg·g−1, respectively. Moreover, mechanisms mainly included hydroxide/carbonate precipitation, complex formation hydroxyl groups, ion exchange. Meanwhile, had ability immobilize metals soil. surface-rich functional groups cation exchange promoted transformation active ions into more stable form.
