Özet

Atomic absorption spectrometric determination of chromium, iron and lead in urine were performed in the present work, after separation and preconcentration procedure including calmagite chelates of the analyte ions on cellulose nitrate membrane filter. The effects of major components of urine including urea, creatine on the quantitative recoveries of Cr, Fe and Ph were discussed. The procedure presented was successfully applied for the determination of these ions in urine samples (recoveries > 95%, relative standard deviations below 10%).
