Abstract

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.
