Preparation of polyaniline (PAn) and its nanocomposite containing nanometer‐size Fe 3 O 4 is discussed, and their capability of separating anions and heavy metals from cotton textile industry waste water is studied. The removal of anions and heavy metals from the waste water was investigated and compared when PAn, nanometer‐size Fe 3 O 4 , and PAn/Fe 3 O 4 nanocomposite were used. The results indicated that PAn and its composite were able to remove the anions and heavy metals. The anion and heavy metal removal percentages were increased by using PAn and nanometer‐size Fe 3 O 4 . The morphology and chemical structure of the adsorbents were investigated by scanning electron microscopy and Fourier transform infrared spectroscopy. J. VINYL ADDIT. TECHNOL., 2010.
