摘      要：Date palm fiber(DPF)derived from agrowaste was utilized as a new precursor for the optimized synthesis of a costeffective,nanostructured,powderactivated carbon(nPAC)for aluminum(Al3+)removal from aqueous solutions using carbonization,KOH activation,response surface methodology(RSM)and central composite design(CCD).The optimum synthesis condition,activation temperature,time and impregnation ratio were found to be 650℃,1.09 hour and 1:1,***,the optimum conditions for removal were 99.5%and 9.958 mgg 1 in regard to uptake *** optimum conditions of nPAC was analyzed and characterized using XRD,FTIR,FESEM,BET,TGA and Zeta ***,the adsorption of the Al3+conditions was optimized with an integrated RSMCCD experimental *** results revealed that the adsorption kinetics data was well fitted by the pseudosecond order model,whereas the adsorption isotherm data was best represented by the Freundlich isotherm *** activated carbon indicated that DPF can serve as a costeffective precursor adsorbent for Al^(3+)removal.
