    The technique of Response surface methodology (RSM) is an integration of experimental strategies, mathematical methods and statistical inference which allows for simultaneous variation of several factors to find the optimal level giving the most interesting response. In this work this method was applied in order to establish the optimum conditions (Al/Li molar ratio, pH and reaction time) for lithium trapping using RSM methodology in presence of Mg2+ ions. The optimum values of these factors were found to be 4, 8.4 and 4h25min respectively. A 24-1 fractional factorial design and central composite design were employed for experimental design and analysis of the results. Predicted values are tested. The obtained results indicate that maximal lithium trapping is 95% and magnesium remaining in solution is 72%. For reducing the magnesium retained in the aluminum gel, washing with distilled water is indispensable. This operation has increased the total percentage of recovered magnesium in solution which reaches 97%. It should be noted that this operation reduces slightly the Li trapping only from 1 to 2%.
