Abstract

Abstract

A novel magnetic composite adsorbent of PAM@Fe₃O₄/MnO₂ (PFM) was prepared and introduced to remove copper ions from water. The effects of adsorbent dosage, initial concentration of the heavy metal solution, and the adsorption time for the Cu²⁺ removal were investigated. The experimental results showed that the magnetic composite adsorbent of PFM could effectively remove copper ions from water. Under the conditions of Cu²⁺ concentration of 50 mg/L, pH of 6.0, and adsorbent dosage of 1.6 g/L, the adsorption equilibrium was gained within 400 min. The adsorption capacity could reach 30.29 mg/g and the removal rate of Cu²⁺ was as high as 97% then. Adsorption-regeneration cycles confirmed that the adsorbent could be reused successfully for Cu²⁺ adsorption and had promising potential for practical application. The VSM analysis showed that PFM had the advantages of superparamagnetism and ferromagnetism. The XRD pattern indicated that PAM adhered to the surface of nano-Fe₃O₄/MnO₂, which enhanced the surface area of contact with metal ions in solution and would be beneficial to the adsorption of metal ions. The amide bonds that appeared in the FTIR spectra analysis indicated that magnetic composite adsorbent was successfully prepared by Fe₃O₄/MnO₂ and PAM.
