Trace amounts of sodum alkylbenzenesulfonate (LAS) in river waters and sediments were determined by high-performance liquid chromatography (HPLC). The dried sediments were refluxed and extracted with methanol-benzeme mixture. After the concentration of the extract the residue was dissolved in hot water, and methylene blue active substances (MBAS) was extracted with 1, 2-dichloroethane using methylene blue colorimetry. Before MBAS was extracted with 1, 2-dichloroethane, some interfering substances were removed by pre-extraction with carbon tetrachloride. LAS in 1, 2-dichloroethane extract was determined by HPLC. LAS in river waters was determined in the similar way. Stationary phase of Shimadzugel PSG-100 and Shimadzu PCH-05 were compared, and it was found that PCH-05 has the following advantages over PSG-100: (i) In river waters and sediments the peaks of LAS were well separated from those of MBAS other than LAS. (ii) Homologous series of LAS with C₁₀C₁₄ alkyl groups were resolved according to the alkyl chain length. (iii) The positionary isomers of phenyl group of LAS were not separated. The method employing PCH-05 was applied to the determination and distribution of homologous series of LAS in river waters and sediment. Recommended conditions for HPLC were as follows: column, PCH-05 (Shimadzu), 4 mm i.d. × 250 mm; mobile phase, 0.08 % (w/v) disodium hydrogenphosphate in 50% ethanol; flow rate, 0.3 ml/min; column temperature, ambient; detector, UV 225 nm. The calibration curve for sodium dodecylbenzenesulfonate was linear within a range of (0.010.3) μg/5 μl (injection volume). The recoveries of known samples were (9199) %.
