Sociedade Brasileira de Química, v. 33, n. 1, p. 146-150, 2010.0100-4042http://hdl.handle.net/11449/25699An analytical method based on high-performance liquid chromatography with electrochemical detection has been developed and applied to the determination of Solvent blue 14 (SA-14) and Solvent red 24 (SV-24) in fuel samples. The dyes were better separated on C18 column, using a mobile phase composed of acetonitrile and ammonium acetate (90:10, v/v). Detection was carried out at an oxidation potential of +0.85V. The detector response was linear at concentration range of 7.50×10-8 - 1.50×10-6 mol L-1 (r = 0.997) for SA-14 and SV-24, respectively. The method was used to quantify these dyes in fuels samples with satisfactory accuracy and precision.146-150porsolvent Blue 14 dyesolvent Red 24 dyefuel analysisDeterminação de corantes marcadores do tipo azo e antraquinona em combustíveis por cromatografia líquida com detecção eletroquímicaDetermination of azo and anthraquinone dyes in fuels sample using hplc with electrochemical detectionArtigo10.1590/S0100-40422010000100027S0100-40422010000100027WOS:000274726800027Acesso abertoS0100-40422010000100027.pdf79278772243268370000-0002-2296-13930000-0003-3032-2556
