Synthesize and characterization of an amido acid functionalized magnetic nanoparticle for heavy metals removal

Wastewater pollution by heavy metals is one the main concerns in wastewater treatment. In last four yearsmodified nano magnetite (Fe3O4) investigated by many researchers for heavy metals removal from aqueous phase. Atpresent study a new amido acid functionalized magnetite (AAFM) and amino functionalized magnetite (AFM) were usedas adsorbents for separation of Cu2+, Mn2+ and Ni2+ from wastewater. The adsorbents characterized by FT‐IR, XRD andSEM. Metal ion concentrations measured by AAS and adsorbents capacity for AFM and AAFM were compared to eachother to determine the effect of the amide and carboxylic groups in metal ions adsorption. The adsorption capacity forCu2+, Mn2+ and Ni2+ at pH=6 were 26, 25, 18 (mg/g) respectively.
