AI Technical Summary
Traditional carbon-based materials have limited adsorption capacity and unstable binding between functional groups and materials, making them unable to effectively remove nitrates. Existing electroadsorption treatments are energy-intensive and lack specific adsorption effects.
A method for preparing ZIF-8 microporous carbon electroadsorbent with multiple modifications was adopted. By modifying ZIF-8-derived microporous carbon with carboxyl and quaternary ammonium groups, its adsorption performance for nitrates was enhanced. The covalent bond between carboxyl and quaternary ammonium groups was used to improve stability and electrostatic adsorption.
It improves the adsorption capacity and selective removal effect of nitrate, has strong anti-interference ability, high adsorbent stability and recycling rate, and achieves selective removal of nitrate in complex water bodies.
