Sy nthesis a nd characterization of polyaniline/HM S nanoco mposite an d study of its activiy for sorption of Ni۲+ fro m wastew ater

Since mesoporou s materials possess high surface ar eas and the size of pores can be tuned within ۲۰–۱۰۰ Å in a very n arrow distrib ution by va rying the p reparation conditions, a large numb er of potential applications of these materials are expecte d to emerge in the are as of catalysis, separati on, adsorpti on and advanced materi als [۱-۳]. In this paper th e nanocom posite including polyaniline conductive polymer supported on hexagona l mesoporous silicate ( HMS) was s ynthesized and characte rized. Then the kinetic study of ads orption of Ni۲+ cations o n the comp osite was inv estigated.
