The procedure is based on cloud point extraction (CPE) of these metals as 2-(bromo-2-pyridylazo)-5-diethyl-amino-phenol (Br-PADAP) complexes into a micellar phase of octylphenoxypolyethoxyethanol (Triton X-114). Optimization of the procedure was performed by response surface methodology (RSM) using a Doehlert design. Principal components (PC) were used to simplify the multiple response analysis. A response surface for the first PC score is useful in determining the optimum conditions for the Cd, Cr, Cu, Mn and Pb determinations whereas the second PC is highly correlated with the Ni response. Improvement factors of 22, 36, 46, 25, 65 and 39, along with limits of detection (3σB) of 0.081, 0.79, 0.38, 0.83, 0.28 and 0.69 μg L−1, and precision expressed as relative standard deviation (%R.S.D., n = 8, 20.0 μg L−1) of 1.5, 2.2, 3.5, 2.6, 2.5 and 2.5 were achieved for Cd, Cr, Cu, Mn, Ni and Pb, respectively. The accuracy was evaluated by spike tests in oil-refinery effluent samples and analysis of a vegetable certified reference material (NIST 1571, orchard leaves). Results found were in agreement with certified values.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2012-07-05T15:52:08Z No. of bitstreams: 1 DD.pdf: 417568 bytes, checksum: 28895758a59a4cdcb2708f8b38c526e3 (MD5)Made available in DSpace on 2012-07-05T15:52:08Z (GMT).
