Biosorption is an extensive technology applied for the removal of heavy metal ions and other pollutants from aqueous solutions. In the present study, the sorption of metal ions from the polluted huge drain (El Tapia drain) in Abu Qir Bay was determined using nano-magnetic iron oxide and nano-silver oxide, low cost and eco-friendly nano-sorbents, which shows a high potential for metal (Cd and Ni) uptake due to the small size of the nano-sorbents, which is favorable for the diffusion of metal ions from the solution onto the active sites of the adsorbent surface. Therefore, Fe3O4 and silver oxide Ag2O nanosorbents can be effective and economical adsorbents for the rapid removal and recovery of metal ions from aqueous media. In this study, we will synthesize magnetic active and silver oxide adsorbents and marine biomass-coated magnetic and silver composites and eval- uate their effectiveness for the removal of toxic metals from one hot spot on the Alexandria coast.
