Tailoring Morphology of MgO with Mg-MOF for the Enhanced Adsorption of Congo Red

ACS Omega, Год журнала: 2024, Номер 9(40), С. 41676 - 41686

Опубликована: Сен. 27, 2024

The active site is a highly anticipated property of adsorbent in the field separation, as it enables concurrent enhancement both adsorption efficiency and rate. Herein, employing morphology-oriented regulation, we successfully fabricated heterogeneous MgO from magnesium-based metal-organic framework (MOF) precursor, octahedral MgO-M laminated sheets MgO-P, for capture Congo red (CR). Specifically, octahedron exhibits greater abundant moderately strongly alkaline sites, which facilitate CR. Furthermore, synergistic effect between lattice oxygen further enhances process. data align more closely with Pseudo-second-order kinetic model Langmuir models. Notably, exceptional capacity (exceeding 1900 mg·g

Fabrication of Plastic Waste-Derived Novel Polymeric Adsorbents for Efficient Arsenic Removal from Water: Pioneering Circular Economy Solutions

Industrial & Engineering Chemistry Research, Год журнала: 2025, Номер unknown

Опубликована: Янв. 2, 2025

Plastic waste, a significant environmental challenge due to its nonbiodegradability, is being transformed as valuable solution for water treatment while promoting circular economy. In this study, polyurethane extracted from plastic waste (code 7) was used fabricate polymeric adsorbents (PWPA) and silica-modified (Si-PWPA) through single-step process using toluene solvent. These were adsorb As(III) ions contaminated water. The characterized HRMS, FTIR, SEM-EDX, XRD techniques, atomic absorption spectroscopy (AAS) measured the AS(III) concentrations. HRMS confirmed successful extraction, characterization revealed porous structures conducive enhanced adsorption. Density functional theory (DFT) provided insights into adsorbents' geometrical energetic molecular properties. maximum adsorption capacities PWPA Si-PWPA 107.52 166.66 mg/g, with 67% 98.78% removal efficiencies, respectively, at pH 7 over 90 min. results demonstrate that derived offer cost-effective efficient method arsenic removal, providing dual pollution recycling.
