Abstract

Abstract : A nanostructured organic–inorganic framework, hexagonal NH2 ‐MIL‐88B, has been prepared through a facile one‐pot reflux reaction and then it was characterized using various techniques. The as‐prepared sample with high specific surface area (414 m 2 g −1 ) showed excellent adsorption for 2, 4, 6‐trinitrophenol (TNP) in the liquid phase. Detailed studies of the adsorption kinetics, adsorption mechanism, adsorption isotherm, activation energy and various thermodynamic parameters were conducted. The adsorption mechanism of NH2 ‐MIL‐88B for TNP may be ascribed to hydrogen bond interaction, and the complexation between ─OH in TNP and unsaturated Fe(III) on the surface of NH2 ‐MIL‐88B. The maximum adsorption capacity of NH2 ‐MIL‐88B for TNP based on the Langmuir isotherm was 163.66 mg g −1 . The as‐prepared NH2 ‐MIL‐88B adsorbent seems to be a promising material in practice for TNP removal from aqueous solution. Abstract : A novel nanostructured organic–inorganic framework, hexagonal NH2 ‐MIL‐88B(Fe), has been prepared through a facile one‐pot reflux reaction and then characterized. The as‐prepared sample with high specific surface area showed excellent adsorption for 2, 4, 6‐trinitrophenol from solution.
