Rapid, selective capture of toxic oxo-anions of Se(iv), Se(vi) and As(v) from water by an ionic metal–organic framework (iMOF)

Fast, selective capture of oxoanions of selenium [Se(iv), Se(vi)] and arsenic [As(v)] by a chemically stable cationic MOF, viz. iMOF-3C, is reported. The compound successfully yields drinking quality water from complicated matrix including river water.
