Magnetically synthesized MnFe2O4 nanoparticles as an effective adsorbent for lead ions removal from an aqueous solution

The adsorption behavior of lead(II) using a new magnetic adsorbent is investigated. The facile synthesis of MnFe2O4 was carried out using the co-precipitation method. The different parameters that affected the adsorption process were investigated such as contact time, metal ion concentration, pH, te...
