Dyes containing industrial wastewater have become an important contamination because of exploitation in various industries such as textile, chemical, refineries and plastic industries [1]. Due to its simplicity, flexibility and low cost, the attraction is one of the most up-to-date technologies and the use of adsorbents has attracted much attention [2]. The nanocomposites was synthesized by graft polymerization of aniline on the modified sheep wool in various ratios of polyaniline to wool. The synthesized nanocomposites were tested for removal of color from aqueous environments. The typical color was methylene blue [3]. The best results was obtained in methylene blue dye. For comparison unmodified natural wool was tested for removal of selected dye for demonstration of nanocomposites efficiencies. The results were summarized in table 1. Fig 1shows the percent of adsorption at different PH. Studies on pure wool and polyaniline-modified wool on methylene blue showed that the removal rate in the presence of pure wool is about %38 and the modified wool is %97 at pH = 5. The prepared nanocomposite was characterized by FT-IR, SEM , TGA and Raman spectroscopy.
