In this study, magnetic iron oxide nanoparticles adsorbent were used to remove lead (Pb)from drainage water. In this way, adsorption isotherm experiments were carried out usingmagnetic iron oxide nanoparticle adsorbent with three replications. The results showedthat magnetic iron oxide nanoparticle adsorbent alone has high capacity for adsorption oflead ions. The results showed that the amounts of qm, Kl , R2 and SEE were 136.20 mg/g,0.01919 lit/g, %99.11, and 4.616, respectively.
