摘要: Abstract The behavior of 56 aromatic-containing organic acids (ACOAs) was obtained under free zone electrophoresis and micellar electrokinetic chromatography using cholic acid as the agent. compound classes encompass phenoxy herbicides, phenylalkanoic acids, aromatic carboxylic sulfonic azo other dyes, ACOAs containing nitrogen. Seven compounds were studied with respect to extraction cleanup from spiked water soil at levels 1.0 0.1 μg/g 100 20 μg/g, respectively. A general scheme isolation developed that used disks solid-phase cartridges. Average recoveries for three determinations ranged 26.5 98.2% relative standard deviations ranging 6.7 55%.
