Luffa cylindrical fibers were used to remove the cationic dye methylene blue (MB) from aqueous solutions. Screening factors which can affect the sorption has been discussed previously. In this study, a response surface methodology (RSM) based on three-level three-factorial Box–Behnken design was used. The effects of three variables, such as the ratio(R) mass of adsorbent/initial concentration of dye, pH0 and size of particles on the adsorption capacity for MB were examined. The optimum conditions (R : 527.27, pH0 : 6 and very fine particle size) for achieving an elimination of 90.04%, were determined by the results of statistical analysis.
