Here we show that the ordered nanoporous alumina has high adsorption capacity for removal of dye pollutants from aqueous solution. The removal percentage of dyes by ordered nanoporous alumina is more than 30% only after 30s and about 60% after 6 min which means that the dye removal is too fast in comparison to the activated carbon. An ordered nanoporous alumina has been synthesized by a fast and facile method by using aluminum iso-propoxide, F127 triblock copolymer and ethanol as a solvent. The TEM, XRD and N-2 adsorption/desorption techniques have been used for characterization and the UV-vis spectroscopy has been used to follow the adsorption process. N-2 sorption measurements reveal that the pore size of the obtained nanoporous alumina is about 5 nm and therefore can be categorized as mesoporous materials. (C) 2012 Elsevier B.V.
