Iron Oxide Nanorod / Polyaniline Nanocomposite for Removal of Amido Black 10b Dye from Aqueous Solution

Shalmali R. Zagade, Sandip T. Mali

Abstract: Dyes used in industries are mutagenic and carcinogenic and have toxic effects on living organisms. The dye effluents need to be treated before discharge to the environment. Present study deals with synthesis of iron oxide nanorods by co - precipitation method. Further the iron oxide nanorods were synthesized with PANI to form nanocomposite and further evaluated for adsorption of hazardous dye Amido black. The FTIR, XRD and SEM analysis of nanocomposite were studied. The effect of adsorbent dose, dye concentration, contact time, temperature and pH and on the adsorption capacity of nanocomposite was investigated using batch experimentation. The maximum efficiency of nanocomposite was observed to be 99 %. The acidic nature of aqueous solution was more suitable for adsorption of dye using nanocomposite. The adsorption was the basic phenomenon involved in the treatment.
