Adsorptive removal of arsenic from aqueous solution by zeolitic imidazolate framework-8 (ZIF-8) nanoparticles

- ZIF-8 nanoparticles have been fabricated via a facile method at room temperature.
- The ZIF-8 nanoparticles show high adsorption capacity for arsenic removal at neutral and basic conditions.
- Electrostatic attraction and hydroxyl and amine groups play key roles in the adsorption process.
