Polyaniline/filter‐paper (PANI/FP) composite was prepared by in situ polymerization of polyaniline onto FP and subsequently evaluated for the removal of Cr (VI) from aqueous solution. Scanning electron microscopy and Fourier‐transform infrared were used to investigate the morphology and physicochemical property of PANI/FP composite. Batch experimental results showed that pH value and temperature could affect the removal capability of PANI/FP composite. Langmuir and Freundlich models were used to analysis the equilibrium adsorption, and both of the two models showed the similar correlation coefficients (about R 2 = 0.9383). Although the removal capability was still limited, the PANI/FP composite showed the great potential that can be used as an effective adsorbent for removing Cr (VI) from industrial waste‐water. POLYM.
