This paper shows effective removal of copper from water and industrial wastewater by modified magnetic nanoparticle with benzotriazole as an efficient adsorbent. The method is fast, simple, cheap, effective and safe for treatment of copper polluted waters. Non-modified magnetic iron oxide nanoparticles (MIONPs) can adsorb up to 49.6% of 50 ng ml-1 of Cu (ΙΙ) ions from polluted water, but modified magnetic nanoparticles improved the efficiency up to 99.7% for same concentration. The required time for complete removal of copper ions was 5 minutes. Variation of pH and high electrolyte concentration (NaCl) of the solution do not have considerable effect on the copper removal efficiency.
