Adsorption of Cu(II) from aqueous solution by anatase mesoporous TiO2 nanofibers prepared via electrospinning

► Anatase mesoporous titanium nanofibers (m-TiO2 NFs) have been synthesized by electrospinning. ► The adsorption kinetics of Cu(II) onto m-TiO2 NFs were the best fitting by a pseudo-second order model. ► The optimum pH for Cu(II) adsorption was found to be 6.0. ► The isotherm adsorption data were well fitted by the Freundlich isotherm.
