Procedure is based on on-line retention of Co(III) ions (generated in alkaline medium by Co(II) oxidation) in a minicolumn packed with a polyether type polyurethane foam loaded with TAC (2-(2-thiazolylazo)-p-cresol) and elution with 2 mol l−1 HCl directly to the flame atomic absorption spectrometer nebulizer. Several chemical and flow variables that could affect the performance of this system were investigated as well as the possible interferents. For 2 min of preconcentration time (10.0 ml of sample volume) the system achieved a detection limit 3.2 μg l−1, a R.S.D. 5% at 20 μg l−1 and an analytical throughput 24 h−1. Whereas for 3 min of preconcentration time (15.0 ml of sample volume) a detection limit 2.4 μg l−1, a R.S.D. under 8% at 10 μg l−1 and a sampling frequency 17 h−1 were reported.Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2013-01-04T14:13:46Z No. of bitstreams: 1 Ferreira.pdf: 106301 bytes, checksum: fb51687666da26d1366781a895ac6a47 (MD5)Made available in DSpace on 2013-01-04T14:13:46Z (GMT).
