Abstract :Abstract. In this approach we explained removal of methylene blue(MB) from aqueous solution as one of the reactive dye stuffs that is useful in textile dyeing. In this research, we optimized the removal procedure of MB from water using modified alumina(Ƴ-Al 2 O 3 ) by Sodium dodecyl sulphate (SDS). In this study a response surface method (RSM) was utilized as an optimization method for optimization of effective parameters of the  experiment. Four factors namely weight of Al 2 O 3 , initial concentration of MB(C 0 ), weight of SDS, and time were considered as main factors in five levels. It is found that all of these factors but C 0 were significant at a certain confidence level (P<0.05).  Then, an empirical model was developed for the removal of MB from aqueous solution by modified alumina. An ANOVA analysis revealed that the validity of the predicted model. Plots of response surface and counter map and interaction plot for the predicted model showed that there was interaction between the weight of Al 2 O 3 with itself. Results showed that the effect of the weight of SDS was the most important factor between the factors. Also the weight of alumina had medium effect among the factors. Finally, the removal of MB from different water samples was successfully done.
