A multielement preconcentration procedure based Fe3O4 magnetic nanoparticles coated with polythiophene(Fe3O4@PTh MNPs) as a solid phase was reported for Cu(II), CII), Cd(II), Ni(II) and Zn(II) ions. Following the preconcentration, the ions were determined by microsample injection system-flame atomic absorption spectrometer (MIS-FAAS). The effect of sample pH, type and volume of eluent, sample volume, extraction time, amount of adsorbent and interfering ions were optimized. The analytes were preconcentrated from 75 to 150 mL of sample solu
