This study made a zirconium-based metal-organic framework (MOF-801) and tested it for removing fluoride from water. It removed up to 92.3% of fluoride with a maximum capacity of 19.42 mg/g and kept about 79% removal after four regeneration cycles. Zirconium release into treated water was not reported.
Key numbers
- Maximum fluoride removal 92.3%; Langmuir capacity 19.42 mg/g; about 79% removal after the fourth cycle (Abstract).
- This paper reports no numerical findings relevant to zirconium exposure.
Methods (brief)
Solvothermal synthesis, PXRD, FESEM, XPS and BET characterization, and adsorption tests varying contact time, dose and fluoride concentration, with kinetic, isotherm and regeneration studies.
Evidence fitness
Off-topic for dietary exposure. The paper uses zirconium as a metal-organic framework adsorbent for fluoride removal; it does not support dietary exposure or toxicity claims for zirconium. The paper did not report zirconium concentrations in treated water.
Limitations
No zirconium was measured in food, water, soil or human samples, so nothing in the paper describes exposure.
