Teixeira, Leonardo Sena GomesSantos, Elenir SouzaNunes, Luana SenaTeixeira, Leonardo Sena GomesSantos, Elenir SouzaNunes, Luana Sena2014-08-13T11:57:13Z20120003-2670http://repositorio.ufba.br/ri/handle/ri/15596v. 722, n. 13Texto completo: acesso restrito. p. 29–33This paper presents an alternative analytical method employing energy dispersive X-ray fluorescence (EDXRF) to determine copper, iron, nickel and zinc ions in ethanol fuel samples after a pre-concentration procedure. Our pre-concentration strategy utilizes analyte retention on cation exchange chromatography paper, a convenient substrate for direct EDXRF measurements. The repeatability, expressed in terms of RSD of standard solutions containing 0.25 μg mL−1 of Cu, Fe, Ni and Zn, and calculated from fifteen consecutive measurements, was 2.5, 2.8, 3.0, and 2.7%, respectively. The limits of detection (LOD), defined as the analyte concentration that gives a response equivalent to three times the standard deviation of the blank (n = 10), were found to be 13, 15, 15 and 12 μg L−1 for Cu, Fe, Ni and Zn, respectively. The proposed method was applied to Cu, Fe, Ni and Zn determination in hydrated ethanol fuel samples collected from different gas stations.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2014-08-13T11:57:13Z No. of bitstreams: 1 Leonardo Sena Gomes Teixeira.pdf: 291227 bytes, checksum: 0f7131c162a95a0946401d2862cebd59 (MD5)Made available in DSpace on 2014-08-13T11:57:13Z (GMT).
