Highly stable mesoporous Co/Ni mixed metal-organic framework [Co/Ni(μ3-tp)₂(μ2-pyz)₂] for Co (II) heavy metal ions (HMIs) remediation.

ABSTRACT: A bimetallic cobalt/nickel-based metal-organic framework (MOF), [Co/Ni(μ3-tp)₂(μ2-pyz)₂], denoted as Co/Ni-MOF, has been successfully prepared by a hydrothermal method. The MOF was prepared by incorporating mixed O^- and N^- donor ligands, specifically terephthalic acid (tp) and pyrazine (pyz). The Mesoporous Co/Ni-MOF was comprehensively characterized using various analytical methods such as XRD, BET, FT-IR, TGA (23 % char yields), SEM, and EDS analyses. The synthesized mesoporous Co/Ni-MOF was then used to absorb Co (II) from aquatic areas efficiently. Several critical parameters, such as the beginning Co (II) concentration (25-150 mg/L), the effect of pH (2-10), the duration of time (5-30 min), and the amount of adsorbent (0.003-0.02 g), were sy
