Facile preparation of hybrid porous polyanilines for highly efficient Cr(vi) removal.

ABSTRACT: In the present work, leucoemeraldine-based hybrid porous polyanilines (LHPPs) have been synthesized by the Friedel-Crafts reaction of leucoemeraldine and octavinylsilsesquioxane (OVS) for Cr(vi) removal. The resulting LHPPs were characterized by Fourier transform infrared spectroscopy, powder X-ray diffraction, thermogravimetric analysis, scanning electron microscopy and N₂ adsorption-desorption. The findings indiated that the LHPPs were amorphous, with apparent surface areas (S _BET) in the range of 147 to 388 m² g^-1 and total volumes in the range of 0.13 to 0.44 cm³ g^-1. Cr(vi) removal experiments displayed that the LHPPs exhibited highly efficient Cr(vi) removal performance. The maximum Cr(vi) removal capacity of LH
