A simple and rapid enrichment/separation procedure for the determination of copper, nickel, lead and chromium in urine samples has been proposed. The analyte ions were preconcentrated on Amberlite XAD-2000 as 1-(2-pyridylazo) 2-naphtol (PAN) chelates. The influences of the main components of urine as interferents were investigated. The present method was applied for the determination of Cu, Ni, Pb and Cr in urine samples of six people randomly selected in Kayseri and Nigde-Turkey with satisfactory results (recovery >95% and relative standard deviation <10%).
