ResumoMetal-organic framework Zr6O4(OH)4(BTC)2(HCOO)6 (MOF-808) nanoparticles were successfully synthesized with a household microwave oven in less than 5 min of irradiation time. The obtained MOF-808 nanoparticles exhibited high superacidity, making them excellent adsorbent for arsenic removal. The adsorption capacity of the as-synthesized MOF-808 nanoparticles for arsenic was 24.83 mg/g. Furthermore, the adsorbents still maintained 82.10% of the removal efficiency after five cycles, indicating that the MOF-808 nanoparticles can serve as a regenerable As(V) adsorbent.
