| 英文摘要 | In this study, zeolitic imidazolate frameworks (ZIFs) sorbents with three different morphology (cubic ZIFs, leaf-shaped ZIFs and dodecahedral ZIFs) were successfully synthesized in aqueous solution via green methods at room temperature and tested for removal of As(III). The ZIFs are all high crystalline, and with a BET surface area of 958.4, 12.7 and 1151.2 m(2)/g for cubic ZIFs, leaf-shaped ZIFs and dodecahedral ZIFs, respectively The experiment revealed that all three adsorbents exhibited excellent adsorption capacities of As(III) despite distinct specific surface area and morphology. The adsorption isotherms of cubic ZIFs, leaf-shaped ZIFs and dodecahedral ZIFs were generally fitted by Langmuir model and the maximum adsorption capacities were 122.6, 108.1, 117.5 mg/g, respectively at pH 8.5. At initial concentration of 200 mu g/L, As(III) was rapidly decreased to below 10 mu g/L by the three ZIFs in 2 h at a adsorbent dosage of 0.2 g/L. It was found that zinc hydroxyl substitution was the main surface complexation method for As(III) adsorption onto the three ZIFs evidenced by the FTIR and XPS results. (C) 2015 Elsevier B.V.
