The Zn(II) sorption rate on the solid support is constant for flow rates ranging from 0.70 to 2.2 ml min−1, but for Ni(II) the sorption rate decreases with increasing flow rate. A flow system was designed to perform sequential measurements at two different flow rates (0.85 and 1.9 ml min−1). The absorbance was measured at 595 nm, where both TAN-immobilized complexes showed maximum absorption. The coefficients of variation were estimated (n=10) as 1.1 and 1.7% (at 1.9 ml min−1) and 1.2 and 2.1% (at 0.85 ml min−1) for zinc and nickel, respectively. This strategy was applied to determine zinc and nickel in copper-based alloys and the results agreed with certified values at the 95% confidence level. The sample throughput was estimated as 36 h−1.Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2013-01-15T11:08:19Z No. of bitstreams: 1 Teixeira.pdf: 112406 bytes, checksum: cb7027d7ce3cd5c1dd0aaf14d4f55cd6 (MD5)Made available in DSpace on 2013-01-15T11:08:19Z (GMT).
