【Abstract】 A method for determining trace amounts of aninoic surfactants using on-line solvent extraction-flow injection fluorimetry has been developed. The linear range of determination is 0. 01-0. 20 mg/L. The sampling rate was 20 sample/h. The method has been used to determine trace anionic surfactants in water samples with satisfactory results.更多还原
