A new method has been established for the pre-enrichment of trace heavy metals(lead(II), cadmium(II), chromium(VI) and nickel(II)) by magnetic iron oxide(core) / zirconium dioxide(shell) and determined by inductively coupled plasma atomic emission spectrometry (ICP-AES) in water samples. The factors affecting the separation and pre-enrichment of analytes such as amounts of magnetic iron oxide / zirconium dioxide, elution time and interfering ions were studied. The detection limits of the method (3σ) were 13.5ng/mL, 1.01ng/mL, 2.94ng/mL and 3.31mg/L respectively for lead(II), cadmium(II), chromium(VI) and nickel(II). The results showed that this method was simple, accurate, and sensitive which could be applied for the pre-enrichment, separation and determination of trace heavy metals in all kinds of water samples.
