| Popis: | Nanosize Copper Ferrite (CuFe2O4)(CF) was prepared by coprecipitation and calcination at 500 °C. A nanocomposite of CF-Polyaniline was synthesized by insitu method and analyzed by X-ray diffraction, FTIR spectroscopy, SEM and photoluminescence spectroscopic techniques. Dielectric constant of CF-PANI was also measured at different frequencies and temperature. CF-PANI was used for removal of Cr (VI) ion from aqueous solution. Effect of contact time, doses of CF-PANI and Cr(VI) ion concentration, pH of Cr(VI) ion solution and temperature on the removal of Cr(VI) ion from aqueous solution was investigated. Maximum adsorption was at pH 2. Out of number of adsorption and kinetic models, Langmuir isotherm and pseudo 2nd order kinetic models fitted the data best. Thermodynamic quantities were also calculated. |
