Abstract :
In this research, the removal of malachite green dye from Textile Wastewaters using polyaniline
coated onto sawdust (PAni/SD) has been investigated. Ammonium peroxodisulphate was used as
chemical oxidant for polymerization of polyaniline directly on the surface of sawdust. The effects of
some important parameters such as pH, initial concentration, sorbent dosage, exposure time and
temperature on uptake of malachite green dye were investigated.Adsorption studies have shown that
pH of the malachite green solution has influence on the dye removal capacity of PAni/SD. It was
found that effective dye removal is occurred under neutral or acidic conditions. The treatments of
data were carried out using both Freundlich and Langmuir adsorption isotherms.
