Typha domingensis phytomass is used as a biosorbent for aluminium ions removal from aqueous solution. A full 2 3 factorial design of experiments is used to obtain the best conditions of biosorp-tion of Al 3þ from water solutions. The three factors screened are temperature, pH, and biosorbent dosage. Two levels for each factor are used; pH (2.5 and 6.0), temperature (25 and 45 C), and phy-tomass loading weight (0.5 and 1 g/50 ml). Batch experiments are carried out using 50 ml solu-tions containing 7 mg/L Al 3þ simulating its concentration in a real wastewater effluent. Aluminium concentration in solutions is determined using ICP-OES; the removal percentages of aluminium are then evaluated. The results are analyzed statistically using the Minitab 15 statis-tical software to determine the most important factors affecting aluminium removal. The results revealed that pH is the most significant factor affecting aluminium ions uptake onto Typha phytomass.
