摘要

An iron-based-organic framework (MIL-101(Fe)) was prepared using a simple one-pot method, aiming to simultaneously oxidize ROX through activating hydrogen peroxide and adsorption formed arsenate under simulated sunlight. The photoassisted MIL-101(Fe) (250mg/L) activating H₂O₂ (1.0mmol/L) system could remove 95.27% of ROX within 120min. Moreover, the arsenate (As(V)) formed in this system could be adsorbed onto the surface of MIL-101(Fe) with 84.14% of the total arsenic removal ratio. The main formed reactive oxygen species •OH and O₂^•- free radicals, attacked the As-C bond of ROX, generated As(V) and o-nitrophenol compounds and accelerated the removal process. The actual environment water matrix significantly promoted the removal ratio of ROX in this system.
