英文摘要Metal organic frameworks (MOFs) combined with adsorptive materials have proven their prospect for radionuclide sequestration. To achieve more void space of MOFs as active sites for U(VI) capture, ZIF-8 (zeolitic imidazolate framework-8) nanoparticles were decorated on the polypyrrole (PPy) nanotubes (denoted as PPy/ZIF-8) via an easy and green method. X-ray diffraction, transmission electron microscopy, and Fourier transform infrared spectroscopy were applied to evaluate the effectiveness of the preparation of PPy/ZIF-8. This novel PPy/ZIF-8 was evaluated for the capture of U(VI) from the simulated wastewater. Based on the Langmuir model, the adsorption capacity was 534.0 mg/g at pH 3.5, which surpassed many other MOF-based adsorbents. The kinetic analysis disclosed that 90 min was enough for PPy/ZIF-8 to reach the adsorption equilibrium. In addition, the introduction of polypyrrole nanotubes endowed PPy/ZIF-8 high adsorption performance in a relatively wide pH range from 3.0 to 7.0. The superior adsorption performance was predominately traceable to the coordination of U(VI) with pyrrolic -NH- groups and Zn terminal hydroxyl groups based on the systematic spectroscopy characterization. PPy/ZIF-8 also showed excellent selectivity and regeneration ability. The excellent adsorption performance endows this novel composite a promising scavenger for the purification of U(VI)-polluted wastewater. (C) 2018 Elsevier Ltd. All rights reserved.
