  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.

  In recent decades, with the rapid growth of urbanization and population growth in cities, the use of public transport and personal vehicles has been on the rise, which has many consequences such as greater dependence on the car, long travels, increased transportation costs and most importantly, environmental hazards and air pollution. The Irregular use of cars leads to the loss of irreversible energy, the effects of greenhouse gas, and the dissatisfaction of townspeople of the high levels of noise and air pollution, resulting in a reduction in economic efficiency. In this regard, governments have set various rules and standards for reducing car pollution and the car makers are required to comply with them. These requirements have prompted carmakers to find ways to reduce the environmental pollution of their products and to create new technologies in this industry. Therefore, attention to environmental studies in the automotive industry is one of the most important factors. In this research, we investigate the types of pollution caused by automobile industry and practical ways to reduce these contaminations. Manuscript profile

  In recent years, the expansion of industries has led to increase industrial wastewater production and environmental pollution. Dyes materials are one of the most important pollutants in industrial wastewater. Today, dyes are widely used in various industries such as textile, paper, leather, printing, and cosmetics. Drainage of colored wastewater does not only affect the aesthetic aspect of the receiving water but also reduces the process of photosynthesis. Also, the colors and their intermediate products are toxic, carcinogenic and mutagenic for aquatic life. Most of these dyes cause skin allergies, dermatitis, and itching, and accelerate the incidence of cancer and mutation in humans. Therefore, industrial wastewaters containing dye need to be treated prior to discharge into the receiving environment. The purpose of this study was to provide a summary of the most important industrial dyes, the health and environmental effects of dyes as pollutants, and to describe the methods for their removal from water and wastewater. In this study, different dye removal methods such as biological, physical and surface adsorption methods were described and the best process for treatment of colored wastewater was introduced considering the economical cost.

  Many of the pollutants in water are known to be harmful for human health and toxic for environment. Among these pollutants, Arsenic is more important because millions of people are exposed to contaminated drinking water. The World Health Organization (WHO) has identified the permitted limit of below 0.01 mg/L (10 micrograms per liter) for arsenic in drinking water and the same amount for arsenic has been reported in Iran's 1053 standard. In this study, various techniques have been investigated for removing Arsenic and efficiency of different nanoparticles in treatment of Arsenic from drinking water. Common methods of removing Arsenic from water sources are including oxidation, coagulation and flocculation, reverse osmosis and ultrafiltration, ion exchange, phytoremediation and new technologies based on the use of nanoparticles. The findings showed that despite of the high arsenic removal percentage using different methods such as oxidation, ion exchange and floating with dissolved air, these methods are not economic and a lot of time is required to achieve optimal efficiency. Recently, the use of nanoparticles has become very popular, so that metal oxide nanoparticles such as magnetic iron, Zinc, Copper, Serum, and Aluminum can completely eliminate Arsenic soluble with a high concentration of 50 mg/L in water sources and after the adsorbent is saturated, it is possible to use the regeneration of adsorbents, repeatedly by adsorbing the pollutant into the adsorbent. As a result, the use of nanoparticles is better than chemical processes and is economic due to their high efficiency in a short time. Manuscript profile
