Fe(II), Ni(II) and Zn(II) form color complexes with 1-(2-thiazolylazo)-2-naphthol (TAN), immobilized on a C18 bonded silica support, at pH 6.4. The proposed procedure is based on the different reaction/retention ratios of the studied ions on the solid support. Bilinear spectrophotometric data of the analytes, fixed in the solid support, were recorded in the 400-800 nm wavelength range as a function of time and a partial least squares (PLS-2) algorithm was used to predict results of synthetic samples. The calibration set employed was integrated by 8 ternary mixture standards and a blank solution. Mixtures containing 0.040 to 0.20 mg L-1, of each species, were successfully resolved, using 3 factors for each analyte and a restricted number of absorbance data obtained in the wavelength range from 560 to 650 nm.Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2012-12-17T15:19:10Z No. of bitstreams: 1 9490.pdf: 361368 bytes, checksum: cd57d9213b01b9f6dea67078a113a718 (MD5)Made available in DSpace on 2012-12-17T15:19:10Z (GMT).
