Abstract

 Control of polluted water has become increasingly important in recent years. Therefore, in this research, previous studies were reviewed to remove the methylene blue dye from its aqueous solution, as it is a very widely used dye, especially the textile industry and polluting the aquatic environment.The use of physical and chemical treatments such as reverse osmosis, membrane filtration, coagulation and reagents are not economic processes. Therefore, the removal process were carried out using different methods and the most prominent and broadest of these methods was adsorption technology due to the low cost of this process and the availability of different bio-adsorbents in addition to the ability of these materials to adsorption.This technique includes the use of different operating conditions such as the weight of the adsorbent material, the pH of the solution, the initial concentration of the dye, the temperature and the contact time required for reaching to equilibrium.It is clear from the results of the experiments shown by previous studies discussed here that there are many adsorbents with low costs that showed good capabilities in removing the methylene blue dye.
