A polyaniline-mixed metal (Fe-Mn-Zn) oxide (PANFMZO) nanocomposite adsorbent is synthesized and characterized by FTIR, SEM, SEM/EDX and Brunauer–Emmett–Teller (BET) analysis. Efficiency of PANFMZO as adsorbent for removal of Cu(II) ions from aqueous matrices is analysed. The parameters like change in amount of adsorbent, contact time, pH and initial Cu(II) ion concentration are studied and removal of 69.20% of Cu(II) ion from test solution is achieved. The maximum adsorption capacity of PANFMZO for Cu(II) is found to be 75.1879 mg/g. The adsorption results are described by both Langmuir and Freundlich isotherms, the data fits better with Freundlich isotherm (R2 = 0.9998).
