in mixture of water and acetonitrile in 50/50 volume ratio was
studied. Synthesized polyaniline in powder shape is used as an
adsorbent to remove toxic hexavalent chromium from aqueous
solutions. Experiments were conducted in batch mode with different
variables such as agitation time, solution pH and initial concentration
of hexavalent chromium. Removal mechanism is the combination of
surface adsorption and reduction. The equilibrium time for removal
of Cr(T) and Cr(VI) was about 2 and 10 minutes respectively. The
optimum pH for total chromium removal occurred at pH 7 and
maximum hexavalent chromium removal took place under acidic
condition at pH 3. Investigating the isothermal characteristics showed
that the equilibrium adsorption data fitted both Freundlich-s and
Langmuir-s isotherms. The maximum adsorption of chromium was
calculated 36.1 mg/g for polyaniline},
