摘要：
A novel self-contained system, dynamic column solid-phase extraction (DC-SPE), for the facile extraction and concentration of five widely used synthetic food dyes is described. The determination of the DC-SPE-extracted dyes in both standard solutions and commercial products was done by rapid square-wave voltammetry and by liquid chromatography in the concentration ranges 1.0 x 10(-6)-2.0 x 10(-5) M and 1.0 x 10(-5)-1.0 x 10(-4) M, respectively. The method of standard additions was used to determine recoveries for several commercial products.
