Development of an HPLC-UV/Vis method for the determination of dyes in a gasoline sample employing different pre-treatments
(Elsevier B.V., 2010-09-01)
A simple method was developed for the determination of the dyes Solvent Blue 14 (SB-14), Solvent Orange 7 (SO-7) and Solvent Red 24 (SR-24), based on high-performance liquid chromatography (HPLC) coupled with UV-Vis ...

A square-wave voltammetric method for analysing the colour marker quinizarine in petrol and diesel fuels
(Elsevier B.V., 2007-01-01)
This work presents an electroanalytical method based on square-wave voltammetry (SWV) for the determination of quinizarine (QNZ) in a mixture of Britton-Robinson buffer 0.08 mol L-1 with 30% of acetonitrile. The QNZ was ...
