The iron(II)—Br—PADAP system at the same conditions forms a chelate with absorption peaks at 560 and 748 nm. This allows the simultaneous spectrophotometric determination of nickel and iron by measuring the absorbance at 560 and 748 nm. The proposed method, at ph 4.0–5.7, shows a molar absorptivity of 1.22 × 105l · mole−1 · cm−1 for nickel at 560 nm and 8.20 × 104l · mole−1 · cm−1 at 560 nm and 3.35 × 104l · mole−1 · cm−1 at 748 nm for iron(II). Beer's law is obeyed up to 0.40 μ/ml of nickel(II) and up to 0.65 μ/ml of iron(II). Thiosulphate as masking agent allows the simultaneous determination of iron and nickel in the presence of high concentrations of copper. The ethylene glycol 2-(2-amino-ethyl) tetracetic acid provides the elimination of many other interferences. The method has been applied successfully to the simultaneous determination of nickel and iron in reference samples.Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2013-02-22T12:38:00Z No. of bitstreams: 1 Costa.pdf: 426404 bytes, checksum: a3ae2d142d33a68c5226b2fa30195aee (MD5)Made available in DSpace on 2013-02-22T12:38:00Z (GMT).
