“…Several methods have been employed to reduce the concentration of acetone such as adsorption, condensation, incineration, catalytic oxidation, etc [6]. Among these technologies, adsorption is considered as an effective and environment-friendly technique to control acetone emissions [7]. Especially, for industry concentration level, adsorption method has the advantages of simple operation, high adsorption efficiency, great design flexibility, low cost, etc [8][9][10].…”

Substantial attempts have been undertaken for the improvement of the air quality over decades; and Volatile Organic Compounds (VOCs) from the chemical and textile industries are truly listed as severe issue to be controlled. To come up with modus operandi for this issue, a novel composite of metal organic frameworks (MOFs) MIL-100(Fe) with salient tuned features of natrite was designed by a green and facile method. Mineralized composite MIL-100(Fe) exhibited enhanced crystallinity than pure MIL-100(Fe) as well showcased a higher surface area of 1300 m2g− 1. Through dynamic acetone pressure swing adsorption setup, MIL-0.05Na revealed an enhanced acetone adsorption of 210 mg g− 1 at room temperature. Gas phase adsorption isotherms confirmed the mono layer adsorption behavior. The kinetics models evaluated that the external mass transfer was the rate limiting step for surface adsorption. The thermodynamic study manifested that the adsorption reaction was spontaneous and exothermic. The proposed mechanism of adsorption was the act of physisorption which enriched the adsorbents reusability. This research work provides a futuristic vista to design mineralized Fe-MOFs composites for an energy saving adsorbents for VOCs removal.
