Nano-sized _Moringa oleifera_ is considered an effective biosorbent with high surface area from agricultural waste, low coast and environment-friendly which can be used for removal of Pb2+ from waste water. Thus our study stem to investigate the ability of natural nano-sized biosorbents for removing very toxic Pb2+ ions from aqueous solution. The investigated biosorbent (_Moringa oleifera_)was characterized by FTIR, SEM, ...
