The final product (Fe-ZSM-5) was applied in the simultaneous removal of benzene (B), toluene (T) and m-xylene (X) from aqueous solutions. The effect of adsorption parameters including pH solution, amount of dosage, contact time, initial concentration of BTX and temperature versus BTX removal efficiency was assessed under batch experiments. The maximum adsorption capacity of BTX (qmax) was obtained at optimum condition of pH=7 and 90 min (qmax; B=9.16
