  In this research, the ability for removal of methylene blue cationic dye using Electro active polymers based on polypyrrole (PPy) and poly (3-methylthiophene) (P3MTh) in a batch system were studied. Sawdust (SD) was made from wood, after patching, as a holder for coating polymers and Sodium Dodecyl Sulfate Anionic Surfactant (SDS) was used to modify the surface of the sawdust. The effects of some important parameters such as pH, initial concentration of dye and contact time were investigated. To evaluate the obtained data, adsorption isotherm curves (Langmuir and Freundlich) were used. The adsorption efficiency for methylene blue was maximized at alkaline pH. Adsorption capacity increased with increasing initial concentration and contact time. In all cases, the adsorption process complies with Langmuir isotherm and represents the homogeneous and single-layer process. Also, the adsorption capacity obtained in SD/PPy, SD /PPy / SDS and SD / P3MTh polymers were 59/52, 400 and 1000 mg/g, respectively. Based on the studies and the results obtained in this study, it was found that these polymer materials can effectively be used in waste dyes, such as textile industry, which they have the great environmental significance.

  These days, the removal of various dyes from industrial wastewater has become an important concern. Synthetic dyes used in industries such as textiles are complex, toxic and mutant organic materials. Congored is also an acidic dye that is considered a high- risk source of contamination and threatens the lives of humans and other living organisms. Different methods, such as electrochemical, physical and biological processes, are used to remove organic pigment from aqueous samples. Adsorption is one of the most effective modern methods of industrial wastewater treatment, which is a relatively simple and inexpensive process that produces non- toxic and low- risk products. The purpose of this study is removing the Congored dye from aqueous solutions and reviewing the accomplished researches for remove it. Manuscript profile
