Methylene Blue Dye Removal from Water by Nickel Ferrite Polyaniline Nanocomposite

Abstract

Textile industries discharge wastewater containing lot of dyes including Methylene blue (MB). These dyes are harmful for human health. Therefore, a number of techniques have been employed to remove the dye from water/wastewater. Out of various methods, adsorption technique was found to be very effective particularly when nanocoposites are used as an adsorbent. In this study Nickel ferrite-polyaniline nanocomposite (NF-PANi NC) was prepared and characterized by different techniques. MB was removed by NF-PANi NC adsorbent and the percent removal was found to depend on MB concentration, adsorbent amount, time and pH of solution. Adsorption and kinetic models were tested and thermodynamic quantities were determined.
