Abstract: MTBE or Methyl Tertiary Butyl Ether is an organic compound, which is used to increase the gasoline Octane Number. At the beginning of 80’s, by discovering the undesirable effects of tetra ethyl lead usage in fuel, MTBE started to be used worldwide. But gradually the undesirable effects of MTBE on environment had been revealed. There are many technologies for MTBE removal from polluted water. Adsorption is the most conventional and economical technology. In this research, some experiments have been done for studying the adsorption of MTBE on different solid adsorbent in batch process. In these experiments a fixed amount of adsorbents including Granular Activated Carbon (GAC), Powdered Activated Carbon (PAC) and the Husk Rice Carbon (HRC) have been put in different one litter covered vessels containing water polluted with known initial MTBE concentration and stirring them. By measuring MTBE concentration in the vessel at different times the effect of different operating parameters such as temperature and pH have been studied on adsorption and optimum condition have been determined. The batch experimental results have been used to calculate the constant parameters of Freundlich and Langmuir adsorption isotherm equations for these systems
