| Abstract | The present work deals with the development of a novel method for the removal of dyes from aqueous solution by using Polyaniline (PANI)-Fe2O3 nano-composite. It is successfully synthesised in situ through self polymerisation of monomer aniline. Adsorptive removal studies are carried out for water-soluble carcinogenic acid violet 19 (acid fuchsine) dye by using PANI-Fe2O3 nano-composite in aqueous solution. Different parameters like dose of adsorbent, contact time and pH have been studied to optimise reaction condition. It is observed that adsorptive removal by PANI-Fe2O3 nano-composite is more effective and faster mode of removing Acid violet 19 dye from aqueous solution than work done before. The optimum conditions for the removal of the dye are initial concentration 20 mg lt -1 , adsorbent dose 10 gm lt -1 , pH 8. The adsorption capacity is found 7.7 mg g -1 . The EDS technique gives elemental composition of synthesised PANI-Fe2O3. The SEM and XRD studies are carried for morphological feature characteristics of PANI-Fe2O3 nano-composite. Besides the above kinetics and isotherm studies have also been carried out. |
