The adsorption process of methylene blue (MB) onto blast furnace slag (BFS) based zeolite (BFSZ) was discussed. Via the analyses of XRD, FE-SEM, XRF, CEC and SSA, the main composition in in the product was Na-A zeolite. And the Na 2 O content, CEC value and SSA value of the BFSZ samples was significantly increased to 19.61 wt.%, 3.06 meq/g and 27.55 m 2. g 1 respectively. Moreover, the adsorption kinetic for MB onto BFSZ was examined and best represented by Pseudo-second-order kinetic model. Moreover, the adsorption capacity of MB from aqueous solutions reaches up to 21.89 mg . g 1 at 30 °C.
