摘要：

The reaction of Fe(II) with 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (Br-PADAP) is studied in detail and procedures for the sensitive determination of Fe(II) at pH 4.7 (acetate buffer), pH 9.0 (borate buffer) and in the presence of EDTA are optimized. A simultaneous determination of Fe, Cu, Zn, Co and Ni in aqueous medium and of Fe, Cu and Zn in blood serum with Br-PADAP at pH 9.0 using multivariate calibration with PLS evaluation of absorbance data also give satisfactory results.
