Oil-in-water micro-emulsions (three-component solutions) were prepared using a mixture of sample, propan-1-ol and HNO3. No additional sample pretreatment was required. In the procedure, three successive 30 μL micro-emulsion aliquots are delivered to the graphite tube. The pyrolysis and atomization temperatures were set to 400 °C and 1400 °C, respectively. The calibration curves showed a linear response up to analyte concentrations of 150 μg L−1 with a correlation coefficient of 0.993. The precision calculated from fifteen consecutive measurements and defined as the coefficient of variation of solutions containing 5.0 and 30 μg L−1 of Hg were 6.4% and 4.7%, respectively. The limit of detection (LOD), defined as the Hg concentration that gives a response equivalent to three times the standard deviation (s) of the blank (n = 10), was found to be 0.78 μg L−1. The proposed procedure was used for mercury determination in naphtha feeds processed in Braskem S.A. (Salvador, Bahia, Brazil).Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2013-06-19T14:12:09Z No. of bitstreams: 1 b607274g.pdf: 514273 bytes, checksum: f421561f0f58216024a196c1a5f37881 (MD5)Made available in DSpace on 2013-06-19T14:12:09Z (GMT).
