Abstract
A rapid high-performance liquid chromatographic method for the determination of dehydroabietic acid in kraft mill effluent is described. Selective solvent extraction of the samples with dichloromethane was performed. The samples were isocratically analysed on a Rad-Pak C18 column using 75% acetonitrile in water (0.1% acetic acid added). Detection was carried out at 220 nm and 267 nm on a variable wavelength detector with a detection limit of 0.01 mg/L.
