- Abstract
The present work deals with the development of a new method for the removal of dyes from an aqueous solution using polyaniline (PANI)-FeO magnetic nanocomposite. It is synthesised in situ through self-polymerisation of monomer aniline. Photocatalytic degradation studies were carried out for cationic acid violet 19 (acid fuchsine) dye using PANI-FeO nanocomposite in aqueous solution. Different parameters like catalyst dose, contact time and pH have been studied to optimise reaction condition. The optimum conditions for the removal of the dye are initial concentration 20 mg/l, adsorbent dose 6 gm/l, pH 7. The EDS technique gives elemental composition of synthesised PANI-FeO. The SEM and XRD studies were carried for morphological feature characteristics of PANI-FeO nanocomposite. The VSM (vibrating sample magnetometer) gives magnetic property of PANI-FeO nanocomposite; also FT-IR analysis gives characteristics frequency of synthesised PANI-FeO. Besides the above studies kinetic study has also been carried out.
